Nanotechnology?

We Answered:

Nanotechnology is an expected future manufacturing technology that will make most products lighter, stronger, cleaner, less expensive and more precise.

Tommy Said:

Nanotechnology and Medicine?

We Answered:

I googled "medical nanotechnology" and got over 2 million hits. I just looked at the first few, but I found them to be very interesting. You may find some useful information on MedLine too. You picked a good subject for a paper. Of course I am in the medical profession and a geek to boot so I love that kind of stuff.

Good luck.

Nanotechnology and medicine?

We Answered:

My friend,
Your question requires at least a book to be properly answered.
Let me define Nanotherapy (application of Nanosize technologies in Medicine) for you in simple words and refer you to some of my publications for more in-depth answers :

Anything that can improve health and well being of a living organism, being a human or animal or plant or alike, and has one of its dimensions less than one micrometer is within the realm and scope of NANOTHERAPY.

See these scientific books, articles:

Does anyone know what's the use of nanotechnology in medicine?

We Answered:

Uses of Nanotechnology in medicine;


The biological and medical research communities have exploited the unique properties of nanomaterials for various applications (e.g., contrast agents for cell imaging and therapeutics for treating cancer). Terms such as biomedical nanotechnology, bionanotechnology, and nanomedicine are used to describe this hybrid field.

Functionalities can be added to nanomaterials by interfacing them with biological molecules or structures. The size of nanomaterials is similar to that of most biological molecules and structures; therefore, nanomaterials can be useful for both in vivo and in vitro biomedical research and applications.

Thus far, the integration of nanomaterials with biology has led to the development of diagnostic devices, contrast agents, analytical tools, physical therapy applications, and drug-delivery vehicles.

Diagnostics
Nanotechnology-on-a-chip is one more dimension of lab-on-a-chip technology. Biological tests measuring the presence or activity of selected substances become quicker, more sensitive and more flexible when certain nanoscale particles are put to work as tags or labels. Magnetic nanoparticles, bound to a suitable antibody, are used to label specific molecules, structures or microorganisms. Gold nanoparticles tagged with short segments of DNA can be used for detection of genetic sequence in a sample. Multicolor optical coding for biological assays has been achieved by embedding different-sized quantum dots into polymeric microbeads. Nanopore technology for analysis of nucleic acids converts strings of nucleotides directly into electronic signatures.

Drug delivery
The overall drug consumption and side-effects can be lowered significantly by depositing the active agent in the morbid region only and in no higher dose than needed. This highly selective approach reduces costs and human suffering. An example can be found in dendrimers and nanoporous materials. They could hold small drug molecules transporting them to the desired location. Another vision is based on small electromechanical systems: NEMS are being investigated for the active release of drugs. Some potentially important applications include cancer treatment with iron nanoparticles or gold shells.

A targeted or personalized medicine reduces the drug consumption and treatment expenses resulting in an overall societal benefit by reducing the costs to the public health system.


Tissue engineering
Nanotechnology can help to reproduce or to repair damaged tissue. This so called “tissue engineering” makes use of artificially stimulated cell proliferation by using suitable nanomaterial-based scaffolds and growth factors. Tissue engineering might replace today’s conventional treatments, e.g. transplantation of organs or artificial implants. On the other hand, tissue engineering is closely related to the ethical debate on human stem cells and its ethical implications.

Teresa Said:

What kind of engineering is probably best for going into the nanotechnology field?

We Answered:

Most universities have chemistry, physics, or chemical engineering that do work on nanotechnology.

Below is a link of a place that does research in nanotechnology.

Nanotechnology is really a multi-disciplinary field. I know that a lot of universities have the three fields I have stated above overlapped in order to get a good study of nanotechnology.

A lot of math and programming skills will also help.

In what year do u think nanotechnology will exist in the medicine?

We Answered:

some nanotehnology already is in use by the medical field, one of the most notable though not necessarily nano things is the camera pill.
