What products are on the market today or are expected?

New nanotech applications might include producing: photovoltaics; hydrogen fuel storage; fuel cells; batteries and super capacitors; photocatalytic reductions of carbon dioxide to produce methanol and other liquid fuels; direct photoconversion of light and water to produce hydrogen fuel; super-strong, light-weight, low-cost light-harvesting materials; high-current cables; thermochemical catalysts to generate hydrogen fuel from water; materials and coatings for deep drilling; lighting to replace incandescent and fluorescent lamps; microscopic probes for planetary exploration or for special earth environments.

Biological based products include: biosensors and detectors and nanopore devices for detecting particular types of DNA, RNA and other biological materials; personalized forms of molecular medicine; a vision chip for the blind and other medical devices for direct implantation.

New nano-crystal coatings and nano-computing "smart" surfaces and a new crop of structural plastics, organic resins and nano-powders are possible.
