Chain of tiny electric actuators that are individually addressable by software to enable device's shape changes can have medical use

Firstly, if sensors are tiny and advanced enough, a whole array of such chains can be used in surgery, especially cancer surgery. The array could connect to usb port so that it is controlled with a laptop semi-automatically. Energy and data flows along wires during the surgery.

Secondly, if there is also a way to transmit energy wirelessly or a way to extract / generate electric power from blood's chemical energy, every actuator chain could separate from the controller device after receiving it's configuration file in binary form and continue to inside body autonomously. After that, some directions and/or navigation signals can be transmitted with magnetic field pulses or ultrasound. The insertion may be done in local anesthetic or maybe the device(s) can be injected to a vein upstream from the tumor or from something else that needs treatment.

It would be a tiny device that has even tinier integrated circuit in it, or is itself a tiny integrated circuit that is something other than a chip ( when looking at the definition of IC very carefully ).

It might use a drilling mechanism similar to this to first gain access to the tumor and then shred it:

(time code link)

It would probably be a MEMS device:

Range of possible sizes and lengths is large. Many very different sizes for different uses.

How to use spin coater for deposition of CdS and CdTe on ITO coated glass?

I am making a CdS/CdTe heterojunction photovoltaic, so CdS first and then CdTe. Has it been done before? If yes, can I get some references?
I have only seen papers using it for deposition of TiO2 and we aren't doing that. All the papers just ised CBD and only before that spin coating for TiO2. Also what binders to be used for it? Is PVA recommendable for it?

Could nanotech (or any other tech) make, not grow, living cells?

I'm not talking about bio-ink, where the cells are already there. Nor am I talking about growing an organ, then putting into someone, but actually printing living cells, like what was done in the movie The Fifth Element, Where they printed the whole rest of a person from a bone and hand in gauntlet. There's no way those cells were grown, it happened way too fast

Printing cells someone problematic, it would be like printing a water balloon, with a lot of things in it, like genes, oraganelles, ribosomes/proteins/enzymes, is that even possible? And if so how would it be done?

Nano Emulsion Cannabinoids

Hi,

I work for a company that makes nano emulsion cannabinoids.

I am looking for people who are wanting to add nano emulsions to their products. Does anyone know people that are interested in doing so?

Nanotechnology

Hello my name is Jason Hein recently I've had something strange happened to me that no one has been able to explain. As I did some of my own investigation into nanotechnology I realize that these things are real and they do exist I don't know if they're in every human in the world but I know that they're in me right now I'm trying to look for any whistleblowers or anyone that can help me get to the bottom of what I experienced. I have two witnesses that are willing to testify if need be, though at this point I'm not willing to risk their lives or their identity. I hope the right person can give me some Direction in this matter feel free to comment post reshare like whatever it takes to get my story out!

Demagnetizing human brain

I got a 220V tc-1 electronic degaussing machine to try to demagnetize/disable any possible nanotechnology that may be in my body/brain. Call me paranoid, that's fine. But for future reference and safety of anyone else that has this idea, 1) is it possible that this would work? 2) would it be likely to cause damage

Literature on the typical C/O ratio of graphene oxide produced experimentally or the degree of oxidation

Are there any literature or literature review on the typical C/O ratio or the degree of oxidation of the graphene oxide produced experimentally? Thanks

Interesting topics to research about nanotech/material science?

So I need to come up with a topic to give a 12 minute presentation on for my materials science class. It can be anything about material science or nanotech and I want to do something super interesting, any ideas?

Nano technology VR multiplayer

Hello 😊 ,
My name is Mahran Abid, a final year master’s student in the DEDI program at the Higher Institute of Computer Science and Multimedia in Sfax. As part of my final year project, I am developing a Virtual Reality (VR) training application specifically tailored for nanotechnology.
This application aims to provide an immersive, interactive, and multiplayer training experience in the field of nanotechnology. In order to make this application as beneficial and user-friendly as possible, we have designed a survey to gather your valuable insights.
📄 We are interested in understanding your prior experience with VR and nanotechnology, your expectations from a VR training application in nanotechnology, and the specific features you would find most beneficial.
Your feedback will play a crucial role in shaping the features and functionalities of this application. Please note that all responses are anonymous and will be used exclusively for the development and improvement of this VR nanotechnology training application.
We greatly appreciate your time and valuable input. Thank you for helping us create a better VR training experience in the field of nanotechnology!
Looking forward to your responses.

Nanoparticles application on insects (Bioassay of nanoparticles on insects).

Any nanotechnologist here, I need to ask a few questions relating to application of nanoparticles on insects. I am very new to this field and have zero exposure to it, I know the method to synthesize nanoparticles but don't know how to apply them. Preffered nanoparticles are siilver, silica and zinc. My questions are;

  1. After synthesis , is it necessary to centrifuge the obtained stock solution or the solution can be applied directly.
  2. If centrifugation is necessary, how to make different concentrations of nanoparticles in water. (Any other solvent, please suggest).
  3. What is the best method of application of nanoparticles on insects?

Thanks (any help will be appreciated).

Carbon nanotubes in sensing project - general question about availability / technology readiness

Hi all! I have a question related to nanotechnology, specifically carbon nanotubes (CNTs).

I've been reading some patents and papers concerning the design of lightweight instrumentation for quantifying concentration of biological molecules. I have often found that the authors will describe a sensor array made of functionalized carbon nanotubes, configured in a particular way, so as to target X molecule.

Now, some these papers can be dated from the early 2000s, and others from last year. I understand that CNTs aren't often used outside of research, but I also see they're widely available to buy in different forms (single, multiwalled). So to my questions, what is the state?

How do you go from "bottle of CNTs" to "sensor array with interface to more standardised electronics"? Can you buy "preconfigured CNT molecule sensors"?

Thanks!
