The Nanotech Reddit

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.

Spring Batch for nanorobots

I have an idea To use Spring Batch for nanorobots I shared it with you maybe someone find it useful interesting and continue dev to beat cancer and here what #AI Gemini think about it https://didipostmanprojects.blogspot.com/2025/01/spring-batch-for-nanorobots.html?m=1 Also Spring Batch as a model for Crispr cas9 https://didipostmanprojects.blogspot.com/2024/10/last-gemini-answer-spring-batch-as.html?m=1

What are some future nanotech applications?

I'm making a video essay about nanobots, and something I want to cover is things nanobots cant do yet but may be able to do in the future in biology, chemistry, and physics that would benefit us a lot. So, what are you most excited for?

Is it possible to disperse titanium dioxide nanoparticles into resin without spending a ton of money sonicator

Sonicators are very expensive from what I've seen and I can't justify spending hundreds of dollar on a sonicator I will probably only use a few times. Is there a way to disperse tio2 into resin without a sonicator?

Seeking advice

Hi everyone,

I'm working on a project to create an ultralight bivvy that is waterproof, highly breathable, and extremely lightweight. A bivvy is basically a layer between your sleeping bag and the outside and serves as a light weight stand alone shelter.

My goal is to optimize material properties for outdoor use, reducing weight while maintaining durability and comfort.

I recently reached out to a researcher who published a paper on highly breathable and durable waterproof polyimide electrospun nanofibrous membranes, asking whether nanofibers could be a viable material for my application. They responded that while nanofibers can greatly reduce weight, their intrinsic strength is low, and suggested cross-linking fibers or reinforcing them to improve durability.

Additionally, I received another paper from them on amphiphobic and recyclable electrospun membranes used for air filtration, which discusses methods for creating high-porosity, waterproof, and reusable nanofiber membranes.

My Questions:

  1. Has anyone here worked with electrospun nanofibers for textiles or outdoor gear?
    • What challenges should I expect in terms of durability and processing?
  2. How feasible is it to create a functional bivvy using electrospun nanofibers?
    • Would laminating the nanofiber layer onto a lightweight, porous fabric ruin its breathability?
    • Are there better ways to reinforce the material while maintaining airflow?
  3. If I partner with a university lab, what equipment and processes should I look for?
    • I’m considering reaching out to materials engineering labs near Denver that focus on nanofibers or advanced textiles.

I’d love to hear any insights from materials scientists, textile engineers, or MYOG (Make Your Own Gear) enthusiasts who have experience working with high-performance membranes. If you have experience with nanofiber manufacturing, waterproof coatings, or breathable laminates, I’d appreciate your input!

Thanks in advance!

Nanotechnology coming out of my skin???

This is going to sound very strange, but over the past month or so, there has been 3 or 4 occasions where I’ve picked hard plastic/glass like strand material out of my skin over my whole body. I kniw- WEIRD I’ve never experienced this. Has ANYBODY experienced this? I feel very alone, scared and confused. Haven’t gone to doctor bc I’m afraid they’ll just write it off or tell me I’m hallucinating. I’ve shown my boyfriend he’s seen it, so I’m not crazy. Anyone out there have any thoughts???

Nano tech in the near future.

What do you think the future holds for nano tech in the next 5 to 8 years ? Will we see nano bots used to heal organs ? Deliver necessary hormones to the parts of the body where there are no respirators ? Killing cancer ? Becoming the new cosmetic surgeries?

Please share some ideas to make a nanotech podcast more entertaining and enjoyable for those who are interested in this field

Hey everyone! 👋

I’m in the process of creating a podcast dedicated to the fascinating world of nanotechnology. My goal is to make it not only educational but also fun, relatable, and accessible to a wide range of listeners—from hardcore enthusiasts to curious newcomers.

While I have a few ideas (e.g., guest interviews, storytelling about real-world applications, and exploring sci-fi-inspired nanotech concepts), I’d love to hear from this amazing community:

  • What topics would you be excited to hear about in a nanotech podcast?
  • Are there any formats or styles that you think would make complex concepts easier to digest?
  • How can we integrate humor, storytelling, or pop culture references while staying true to the science?
  • Any favorite podcasts you think we can draw inspiration from?

I really appreciate any opinions from all of you. Thank youu!

I managed to escape from the facility But the nanobots are already insid me

They remotely control my heart
They also can read my thoughts They can real all memories

How safe is it for absolutely inexperienced students to work with nanoparticles?

Hello all, for context, I am 14 years old working on a research project for academic purposes.

I really don't know about the safety of all this and as I read deeper and deeper, I just get more worried...

We're gonna work with a fume hood and some basic PPE and an N95 respirator. (My teacher said that just wear two N95s). Is that all I need?

The nanoparticles in question are titanium dioxide and zinc oxide. Thanks.
