Nanotechnology – the future is now Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. Most applications are limited to the use of "first generation" passive nanomaterials which includes titanium dioxide in sunscreen, cosmetics, surface coatings, and some food products Nanomedicine is the medical application of nanotechnology. Nanomedicine ranges from the medical applications of nan omaterials, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology. Current problems for nanomedicine involve understanding the issues related to toxicity and environmental impact of nanoscale materials. In materials science, nanoparticles allow for the making of products with mechanical properties very different from those of conventional materials and can also improve surfaces by adding new friction, wear or adhesion properties. A wide variety of nanoscale materials and coatings are already in use in consumer products such as cosmetics and sunscreens, fibres and textiles, dyes, and paints. The constant drive towards miniaturization in electronic engineering has led to devices that are well within the nanometre range. Data storage devices based on nanostructures provide smaller, faster, and lower consumption systems. Today's scientists and engineers are finding a wide variety of ways to deliberately make materials at the nanoscale to take advantage of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts.
