Nano Engineering for Next-Gen Drug Development

[markone]

is there any new technology use NANO engineering to create new generation of drugs ?

Many! (You don't need to capitalise the 'nano' btw), here's a list;

Dendrimirs

Liposome capsules (see doxyrubicin http://en.wikipedia.org/wiki/Doxorubicin#Liposomal_formulations)
http://en.wikipedia.org/wiki/Liposome#Applications

Quantum dot imaging techniques

Self-assembling peptides

Scaffolds for tissue engineering

Various drug-delivery systems for photodynamic therapy

Hydrogels (can be used as tissue scaffolds or site-specific drug delivery systems)

And the list goes much further than that. However I should state that whilst there are dozens of drugs that implement some form of nanotechnology in testing and development at the moment doxyrubicin is the only one I know of off the top of my head that is commercial.

Nanomedicine has many areas on which it focuses, here I've tried to give you a list of different methods of drug delivery/imaging. If you were to include medical devices (prosthetics, surgical tools, monitors) or biomedical research equipment (AFM, lab-on-chip, optical tweezers) the list would explode further

thank you
i want ask if any way to use NANO engineering to use DNA parts

(again you don't have to say 'NANO', the correct term is nanotechnology, nanoengineering or nanomedicine).

There are many applications and much research into using DNA and RNA. Wikipedia has an excellent article.

For RNA whilst it's not strictly nanotechnology siRNA can be used in conjunction with nanoengineered systems (i.e. drug delivery) for a wide variety of research and medical applications. The potential for siRNA treatments is astounding, siRNA works by preventing genes forming proteins. This is a fundamental aspect of molecular biology and the ability to manipulate it is highly desirable
