MAGNETIC nanoparticles targeted to nerve cell membranes can be used to remotely control cellular activity and even the simple reflex behaviours of nematode worms, according to research by a team of biophysicists at the University of Buffalo. The new method, which is described in the journal Nature Nanotechnology, could be very useful for investigating how…

Silver nanorod microscopy

Japanese researchers have developed a design concept for a light microscope which could in principle be used for imaging of nanoscale objects. The device would rely on a novel subwavelength imaging technique which allows for the visualization of objects that are smaller than the wavelength of the photons used in the device. Once thought to…

Smart dust refers to a network of wireless, autonomously-acting microscopic devices. Built with microelectromechanical systems (MEMS) and using molecular manufacturing processes, these devices would act as sensors, detecting anything from light and vibrations to chemicals and pathogens, and communicating the information over long distances. Microscopic devices such as this are still hypothetical, and the only…

(Image credit: William Ormerod/ Unversity of Wisconsin-Madison) A recent study into the biophysical properties of a highly reflective and self-organizing squid protein called reflectin will inform researchers about the process of “bottom-up” synthesis of nanoscale structures and could lead to the development of thin-film coatings for microstructured materials, bringing scientists one step closer to the…
