Nanotechnology developments

anotechnology is a relatively new field of research and scientific development. It has been speculated about for decades and the wonders and advantages of nanotechnology have been extolled by many. But not all.
The scientific community, in its never ending quest for information and knowledge, consistently fails to seriously acknowledge the dangers of “invisible” technology, such [...]

Multifunctional nanotechnology device for integrated, cell-based nanotherapy

One of the promises of medical nanotechnology is a drug-delivery nanodevice that can image, target, and deliver drugs to a specific cancer location inside the body and monitor and if necessary adjust the drug release at the target location. Researchers in Taiwan have now designed a nanodevice that comes pretty close to this vision.

“We have [...]

Pushing the envelope in atomic force microscopy

(Nanowerk Spotlight – Application Note) Over the past decade, Atomic Force/Scanning Probe Microscopy (AFM/SPM) has emerged as the leading tool for investigations at the nanoscale – doing everything from imaging, to compositional differentiation, to explorations of molecular forces. But aside from some interesting tweaks, add-ons and repackaging, the field has seen no fundamentally new instruments [...]

nanocomposite for on-demand drug delivery inside the body

(Nanowerk Spotlight) Quite a number of serious medical conditions, such as cancer, diabetes and chronic pain, require medications that cannot be taken orally, but must be dosed intermittently, on an as-needed basis, and over a long period of time. Researchers have been trying to develop drug delivery techniques with ‘on-off switches’ that would allow controlled [...]
