NANOTECHNOLOGY INTRODUCTION
Truly revolutionary nanotechnology products, materials and applications, such as nanorobotics, are years in the future (some say only a few years; some say many years). What qualifies as “nanotechnology” today is basic research and development that is happening in laboratories all over the world. “Nanotechnology” products that are on the market today are mostly gradually [...]
Industrial nanotechnology processes getting closer
For years now, nanotechnology researchers have been promising us carbon nanotubes as the basis for numerous breakthrough applications such as multifunctional high-strength fibres, coatings and transparent conducting films. Not to mention as a cure for cancer (see“Horseradish, carbon nanotubes and cancer therapy”) and a solution to the energy crisis. However, while the thermal, electrical and [...]
Sharper and faster nanodarts kill more bacteria
A newly published antibacterial activity mechanism study demonstrates how a single walled carbon nanotube (SWCNT) kills bacteria by the physical puncture of bacterial membranes. The nanotubes would constantly attack the bacteria in solution, degrading the bacterial cell integrity and causing the cell death. This work elucidates several factors controlling the antibacterial activity of pristine SWCNTs [...]
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 [...]
