Focusing the laser was conducted with the help of small glass spheres, playing the role of the lens. This mechanism allows inexpensively and relatively easy to apply complex patterns to a glass surface, whereby obtaining a spatial resolution of less than 100 nanometers.
Researchers have simulated a new concept for rapid, accurate gene sequencing by pulling a DNA molecule through a tiny, chemically activated hole in graphene and detecting changes in electrical current.
Materials scientists have shown for the first time that the mother-of-pearl in clam shells does not form in a crystallisation process but is a result of the aggregation of nanoparticles within an organic matrix.
New research has led to the use of the nanoprobe to study how individual proteins interact with DNA. Invisible to the human eye, this tiny triangular probe can be captured using laser tweezers and then moved around inside a microscope chamber.
Damage developing in a material can be difficult to see until something breaks or fails. A new polymer damage indication system automatically highlights areas that are cracked, scratched or stressed, allowing engineers to address problem areas before they become more problematic.
Researchers have solved a problem in micro- and nanofabrication - how to quickly, gently and precisely handle tiny particles - that will allow researchers to more easily build tiny machines, biomedical sensors, optical computers, solar panels and other devices.
