2D materials, which consist of a few layers of atoms, may well be the future of nanotechnology. They offer potential new applications and could be used in small, higher-performance and more energy-efficient devices. 2D materials were first discovered almost 15 years ago, but only a few dozen of them have been synthesized so far. Now, [...]
An international research team led by the Institute of Bioengineering and Nanotechnology (IBN) of the Agency for Science, Technology and Research (A*STAR) and IBM Research developed a synthetic molecule that can kill five deadly types of multidrug-resistant bacteria with limited, if any, side effects. Their new material could be developed into an antimicrobial drug to [...]
Future nanomedical devices and systems will have strong potential to enable a broad range of aerospace and space applications. With further dimensional reductions in conjunction with the increased capabilities of nanoelectronics and artificial intelligence (AI), nanomedicine may facilitate the development of a wide array of advanced nanomedical diagnostic and therapeutic capabilities dedicated to the health [...]
Since the early days of nanotechnology in medicine, nanocarriers – nanostructures that are used to transport therapeutic compounds inside living organisms – have been attracting the interest of researchers because of their great potential in targeted drug delivery due to a wide range of possibilities for surface modifications and compatibilization. Another attractive issue of these [...]
Researchers at MIT have developed a new approach to measure electrical activity deep in the brain: using light — an easier, faster, and more informative method than inserting electrodes. They’ve developed a new light-sensitive protein that can be embedded into neuron membranes, where it emits a fluorescent signal that indicates how much voltage a particular [...]
An international research consortium has developed the first computer model to include 3D in the representation of human metabolic processes. To this end, the researchers integrated the three-dimensional structures of over 4,000 metabolic products, or metabolites as they are known, and nearly 13,000 proteins into an existing computer model. They also added an enormous volume [...]
An international team of scientists has developed a water-soluble "warped nanographene", a flexible molecule that is biocompatible and shows promise for fluorescent cell imaging. The new nanographene molecule also induces cell death when exposed to blue laser light. Further investigation is required to determine how nanocarbons could be used for a range of biological applications, [...]
Ingested or injected pharmaceuticals can target specific molecules involved in disease processes, but get distributed throughout the body where they can cause unwanted side effects. An approach known as electroceuticals aims to avoid systemic exposure by using small wires to electrically monitor and manipulate individual nerves that control organ function and carry information about disease. [...]
Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism, and image shift. The research is [...]
A small rectangle of pink glass, about the size of a postage stamp, sits on Professor Amy Shen's desk. Despite its outwardly modest appearance, this little glass slide has the potential to revolutionize a wide range of processes, from monitoring food quality to diagnosing diseases. The slide is made of a 'nanoplasmonic' material -- its [...]
