Nanobiomechanics

Nanomaterial tools are being applied to medicine. Medical researchers have long known that diseases can cause — or be caused by — physical changes in individual cells. For instance, invading parasites can distort or degrade blood cells, and heart failure can occur as muscle cells lose their ability to contract in the wake of a …

Improving tools and imaging capability

There has been advance that allows the gathering of quantitative, real-time information on protein expression in living cells at the single-molecule level. This will allow a deeper understanding of the body and biology at the molecular level. Understanding at a real-time and molecularly precise level is useful to learn how to better control and utilize …

other tech: 3 nanometer channel length transistor

Scientists at the National Nano Fab Center at the Korea Advanced Institute of Science and Technology (KAIST) have developed the world’s smallest transistor, with a channel length of 3-nanometers, according to a Korea Herald report. The device is a three-dimensional FinFET. This will allow the development of terabit memories. It could allow conventional silicon integration …

Towards nanomedicine: Bone Cell grown on carbon nanotubes

Bone cells grown on carbon nanotubes Because carbon nanotubes are not biodegradable, they behave like an inert matrix on which cells can proliferate and deposit new living material, which becomes functional, normal bone, according to the paper. They therefore hold promise in the treatment of bone defects in humans associated with the removal of tumors, …

DNA nanotechnology: DNA oragami example of current capability

Impressive progress is being made towards DNA nanotechnology. A map of the Americas measuring just a few hundred nanometres across has been created out of meticulously folded strands of DNA, using a new technique for manipulating molecules dubbed “DNA origami”. More information is here The “DNA origami” procedure laid out by Paul Rothemund of the …

Physical manipulation of chemistry reactions

Here is more evidence and advancing capability to physically manipulate and effect chemical reactions. Using a chain of molecules as an infinitesimal lanyard to tug on a chemical bond about to break, Duke University chemists have found they can speed a complex chemical reaction Craig’s group used an AFM tip to exert almost infinitesimally small …

Computational chemistry – biology advance: complete virus modelled

Researchers simulate complete structure of virus — on a computer. This is showing an advance of the power and capabilities of computational chemistry and now computational molecular biology. Better computer work can accelerate the progress of the experimental work. The satellite virus they chose is a spherical RNA sub-viral agent that is so small and …

Nanomaterials, Nanoparticles: Nanorice

Nanorice is made of non-conducting iron oxide called hematite that’s covered with gold. The core size and shell thickness vary slightly but the particles are about 20 times smaller than a red blood cell. Nanoparticle’s shape could improve chemical sensing, biological imaging. Nanoparticles like nanorice can be used to focus light on small regions of …

Nanoscale technology: Peptides repair nerve damage. Basis of reconstructive brain surgery

Although victims of stroke and traumatic brain and spinal cord injuries sometimes recover through rehabilitation, they often have permanent disabilities, in part, because scar tissue and regulatory chemicals in the brain slow nerve growth, preventing nerve tissue from repairing itself. Now a treatment that has restored lost vision in lab animals appears to overcome these …
