Researchers at Stanford University have created a nanoscale probe that can be implanted into a cell wall without damaging the wall. The probe can then be used to listen to electrical signals within the cell, as well as possibly provide a way to attach neural prosthetics or to insert medication inside the cell.
Scientists from Buffalo, Cleveland, and Oklahoma City made a huge step toward making the blind see, and they did it by using a form of gene therapy that does not involve the use of modified viruses. In a research report published in the April 2010 print issue of The FASEB Journal, scientists describe how they [...]
A team of McGill Chemistry Department researchers led by Dr. Hanadi Sleiman has achieved a major breakthrough in the development of nanotubes — tiny “magic bullets” that could one day deliver drugs to specific diseased cells. Sleiman explains that the research involves taking DNA out of its biological context. So rather than being used as [...]
Using lasers and nanoparticles, scientists at Rice University have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The scientists used lasers to make “nanobubbles” by zapping gold nanoparticles inside cells. In tests on cancer cells, they found they could tune the lasers to create either small, bright [...]
Many different cell types can be cultivated in a petri dish. Unfortunately, turning them into organs is substantially more difficult. It also tends to be difficult to cultivate cells that will function in a way that is similar to normal tissue function. This is an especially critical issue when it comes to heart cells. Recently, [...]
In a recent announcement by the Proceedings of the National Academy of Sciences, it was declared that an ultra-high-resolution imaging procedure utilizing an X-ray diffraction or a method to “lenseless” X-ray microscopy can now be used to look at bacterial cells.
Biology and electronics have long existed in separate universes. But because biological molecules, like DNA and proteins, are roughly a few nanometers in size, and because physicists and chemists are now learning how to make electronic devices on exactly that size scale, these universes are colliding. The result is a new class of devices that [...]
Diagnostics : Nanotechnology is at the core of advances in the biosensor field through the use of novel materials, improved surface engineering and patterning techniques, and systems integration. Biosensors are being developed using nanowires, nanoparticle arrays and nanofluidics systems – devices are likely to include the integration of many of these components. These materials permit [...]
Nanobiotechnology has the potential to unite the power of molecular biology with integrated circuits while putting the ultra-small techniques of nanofabrication to work in the study and manipulation of biological systems. Nanobiotechnology is especially useful for applications that require small-scale mechanical probes, high-speed response, or measurement of very small forces.
Nanobiotechnology involves implementation of nanotechnology in biomolecules. It involves microanalysis of biomolecules, with a goal of developing miniaturized sensor technologies with optical, electronic and chemical probes to detect and analyze small numbers of molecules in various matrices with high spatial resolution.
