Sensors artificial

Evaluation procedure. Functionality is evaluated either by subjective, semiobjective, or objective methods. The subjective methods utilize exclusively the five senses as sensors and the brain as the value assignor. Objective methods utilize completely artificial sensors and instruments as the value assignors. 

However, in Nanotechnology Research Directions (a report pubfished by the US government in 1999), it was pointed out that current nanoscale technologies are still highly inferior to those seen in natural systems. The efficiency of the energy conversion that occurs in mitochondrial and photosynthetic systems far exceeds those obtained in artificial systems. A dog can smell and a bat can hear far more sensitively than most artificial sensors. The information pro-... 

An emerging area of modem enantioselective analytics is the development of dedicated, target-specific molecular tools that meet the criteria of being robust, high throughput, and specific [105]. Important groups of such tools constitute chiral artificial sensors and receptors as well as polymer-based chiral materials, such as... 

It is commonly known that human tongue is able to distinguish four basic types of tastes (e.g., sweet, salty, sour, and bitter) [167]. Although the human tongue and nose can sufficiently respond to chemical substances, they cannot directly contact with many toxic chemical substances. Artificial sensors, such as electronic tongue or electronic nose, are the possible alternatives for detecting toxic and unpleasant substances. The use of artificial sensors for evaluating tartans... 

Hydrogels are macromolecular materials with a water content of 30 to 90%. They provide fairly good biocompatibility, being adequate materials for catheter sutures, blood detoxificants, artificial sensors, ophthalmologic protection (contact lenses, artificial cornea), conjunctive tissue substitution, bum therapy, dental implants, aesthetic surgery, and immobilization of bioactive agents. 

This is a pity because transport functions have clear implications for new technology. As one example, the current thrust in biosensors seeks to transplant natural transport systems into artificial sensors which could then exhibit the inherent sensitivity of the biochemical apparatus. Can this be extended to other technological goals such as molecular switches or ionic computers Possibly, but the process will be plagued with the problems of maintaining a natural" environment in an artificial...
