Nanotechnology (sometimes shortened to "nanotech") - the manipulation of matter on an atomic and molecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size.
Nanotechnology as defined by size is naturally very broad, including fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc. The associated research and applications are equally diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale.
Scientists currently debate the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.

Hi, I made a post recently about an experience I had in hospital. I was diagnosed with psychosis, but experienced something strange that I can't quite put behind me. Whilst at hospital I heard a voice (maybe it was in my head though) say they were going to recode me, and a weird sensation ran through my body from head to toe. If felt like something was changing. Since then I have limited interoception...I can't feel my stomach rumble when hungry, my period come on, or any bodily aches and pains that I had before. I don't feel my muscle during or after a workout or massage now too. I feel like something was tested on me, possibly nanotechnology used to alter my dna. The post I made recently had lots of people saying nanobots are nowhere near ready to do something like that. I had lots of reassurance that it couldn't be possible, then someone referenced then patent I've linked at the top of this post evidencing that it is possible to alter dna. Could someone please tell me if this does mean that I could have been experimented on, or is it still not possible?
I want to use nano fibers to cut cheese
I'm looking to see if it's a thing to ask those on forums for quality academic resources at free prices, as I have found comprehensive nanotechnology PDFs for free online which span hundreds of pages, but I have recently discovered a snippet from one with approx. 2k pages covering a whole world of aspects. My best guess is that snippet was taken from "Comprehensive Nanoscience and Nanotechnology," which is the prime I had in mind as the presumed most comprehensive modern nanoSTEM textbook, and the one I would love if it can be converted into a PDF and sent online, as it's multiple thousands of dollars, however, I must note that I'm not aware if this conversion of these textbooks to pdf is a thing due to absent knowledge in the area.
I’m in my first year of nanotechnology degree and I’m wondering which are the main companies in the industry and which are the best options to work in the future. Thankss
I want to know of it's possible to alter someone's dna using nanobots. I went into hospital as I was hearing voices. I heard someone say they were going to recode me. When I was on the hospital bed I felt a tingling sensation run slowly from my head to my toes. It felt like my body was being changed. I now don't feel my body as much as before. I don't feel muscles when working out or after. I don't have any knots in my muscles now according to the last massage I had, whereas before I had lots and felt sore the next day. My mind body connection feels broken. Do you think I could be being experimented on with nanobots? How likely would that be? Please help me.
I am a very recent Engineer in Nanotechnology graduate and I am looking to apply to a master program.
My studies were always mainly centered around Chemistry, with a bit of Physics. So I have a lot of experience with laboratory work, doing synthesis of nanostructures and also the process of characterization (XRD, DLS, FTIR, SEM, etc.)
I have always been interested in the area of medicine, specifically stuff surrounding Nanomedicine**,** like drug delivery and overall pharmaceutical sciences that use nanotechnology.
Since I have learned a lot of chemistry and some bio stuff here and there, I think I can apply to some masters in the chemistry or pharmaceutical science area.
On the other hand, I have always dreamed of working at industries like Samsung. Designing chips, electronical devices, medical devices, semiconductors, etc. obviously with a focus on Nanotechnology.
However I don't know what type of master programs I should look for if I am trying to get into that area and also if my main knowledge comes from Chemistry and not really Electronics.
Additionally, I don't really like physics, so maybe this area that I mention is not really for me and I should stick to something with mostly Chemistry or Biology like in the Pharmaceutical Science programs.
I am open to any suggestions, specially in this last area since I don't know how to search for this type of program and I want to be more informed. I am open to all universities around the world (except somewhat the US, but you can still suggest options there).
Hello all, i am a Civil Engineer based in Pune, India. with my own business of supply of construction materials. i am looking for easy, sustainable nanotechnology-based products specifically those that can be used in civil engineer, that i can manufacture in small to medium quantities from my factory. i am willing to invest in the machinery as long as the product has good potential in the future. Please guide me what i can make in an affordable way.
Thank you!
This week I’ve started my major in nanoscience and nanotechnology and Im not sure if I chose the best option. I wanted to study a physics degree but unfortunately I didnt got accepted so instead I got into this major as it has lots of quantum physics and biochemistry subjects that are my main interests right now.
Now Im concerned if I have made the good decision, also Im not sure if will be able to find a job when I finish my major.
Pd: English is not my main language so sorry for my bad english.
Get a photo of your watcher and furiously masturbate to it and I mean really get into it and say the most disgusting sexual you have with said watcher and then approach them in real life and look at them straight in the eyes and see what they do.
Hey, I do research quantum dots for 10 years.
If you have questions I most likely can answer them!
I apologize if this isn't the place to post and ask about but I was curious if anyone was in the same position as me. I recently graduated back in May majoring in Nanoscience and have been struggling to find work. I've been applying to every intern/entry-level position related to my major, from Electrical engineering to materials science, process engineering, process technician, etc, but can't seem to find anything. Did I make a mistake in getting my undergraduate degree in nanoscience? Do people usually get their Masters immediately after graduating? I'm about to start work in retail simply cause I need income and it's the only interview I've gotten.
Ok guys, I'm really curious for any and all opinions, what is this field's biggest challenges atm? I saw a comment saying that nanotechnology isn't real right now because of technological challenges involving actuators or something along those lines? Anything else?
Hello!!!! I'm studying for a degree in nanotechnology at UASLP. I am interested in the synthesis of iron oxide nanoparticles. Does someone have an article on the synthesis of these nanoparticles?
How can I remove nano tech from my body? It’s literally crawling all over my body (including my eyes.. the clear ones).. I can sit here and literally watch & screen record through my iPhones magnifying feature (regular recording ALWAYS replays blurry) these things crawl around my eyes & skin.
NOW.. how can we remove this crap!?
I’m in several groups across many platforms & there’s WAY TOO MANY OF US to deny us anymore!
Can ANYONE do us all a huge favor & deliver us from this evil!? I promise I’ll forever hold you a legend & I’m sure others will be beyond thankful! The medical community turned its back on us, we’re losing hope! Please!! Help!! 🥺🙏
Hi. I am nanoengineering student. Our nanotec professors have not attended to any of our nano classes, so I know nothing about my specialization. What books and materials would you advise for me to read and start learning about nano?
Thanks! Sorry for my English
"I am exploring the use of monolayer graphene as a cutting material for high-precision applications. We know that graphene has exceptional mechanical properties, such as high strength and stiffness, in addition to its extremely thin atomic thickness. I would like to discuss the advantages and challenges of using graphene for cutting at nanometer scales. Does anyone have experience or can share insights into its cutting properties, durability, and potential industrial applications?"
How will nanobots make immortality possible and delay the Hayflick Limit for our body cells indefinitely?
What year will such nanobots be likely to arrive?
I am very ignorant in talking about this subject, so I apologise for any misunderstandings with what I am saying. The baseline is I need help with the pathway to getting into doing what I want which involves nanotechnology.
For context: I am a 3rd year biotech at an Aussie uni.
So firstly, I have an idea of making bio-'nano-bots' that is basically a drug delivery system that contains other nanoparticles (e.g. lipid nanoparticles, have no idea if they are the best nanoparticle drug delivery) hypothetical therapeutic longevity treatment that treats markers of ageing (e.g. methylation clocks, cellular senescence) and these nano-bots can detect in the body when an area needs to be treated next and so can be deployed when triggered. These nano-bots also need 'refills' of the nanoparticles that contain the treatment so there needs to be a way to achieve that also. Any help and advice in my pathway in terms of education, resources or any groups that are working on similar or identical things would be very appreciated and I would be very grateful for!!
Hey r/nanotech ,
I'm curious about the current state of 3D design for molecular systems and nanomachines. I understand that computational simulations and design at this scale are incredibly complex, but I'm wondering if any of you are already working on building these systems.
Specifically, I'd like to know:
I'm really interested in hearing about your experiences and insights. Thanks in advance for sharing!
Hi so I’m working with cadnano to make my origami structure but I’m running into something weird. The boxes behind my scaffold seems to be highlighted some colour for some reason. I don’t know if that’s potentially a problem and I’ve tried searching this up but I can’t seem to find anything. So would any one know what this means?
Hello everyone! I am currently trying to get the Innova AFM by Bruker to get images in STM mode and it's not working! Going through their manual I put all the same parameters and even used a Bruker tip and their HOPG sample but cannot for the life of me get the same results! I am trying to get a 4nm x 4nm of nanoparticles but can't see the particles at all. Its just looking very "noisy". Tried changing out tips and I used the provided cover. I've tried going from 2 micrometers to as low as 1nm x 1nm. No luck! Any ideas or tips?
