List Of Nanotechnology Applications ... Buckyballs can "interrupt" the allergy/immune response by preventing mast cells (which cause allergic response) from releasing histamine into the blood and tissues, by binding to free radicals "dramatically better than any anti-oxidant currently available, such as vitamin E". Tissue engineering Nanotechnology can help reproduce or repair damaged tissue...

Taste ... Humans receive tastes through sensory organs called taste buds, or gustatory calyculi, concentrated on the top of the tongue. Taste is sensed through taste cells, which are known as taste buds...

Full-spectrum Photography ... Modified digital cameras can detect some ultraviolet, all of the visible and much of the near infrared spectrum, as most digital imaging sensors are sensitive from about 350nm to 1000nm...

Sensor ... Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base... Sensors also have an impact on what they measure; for instance, a room temperature thermometer inserted into a hot cup of liquid cools the liquid while the liquid heats the thermometer... Sensors need to be designed to have a small effect on what is measured; making the sensor smaller often improves this and may introduce other advantages...

Holographic Sensor ... Certain molecules that mimic biomolecule active sites or binding sites can be incorporated into the polymer that forms the holographic film in order to make the holographic sensors selective and/or sensitive to certain medical important molecules like glucose, etc...
