SENSOR
• A sensor is an instrument that responds to a physical stimulus (such as heat, light, sound, pressure, magnetism, or motion)
• It collects and measures data regarding some property of a phenomenon, object, or material.
• Sensors are an important part to any measurement and automation application
NANOSENSOR
An extremely small device capable of detecting and responding to physical stimuli and dimensions on the order of one billionth of a meter.
Physical stimuli: Biological and chemical substances, displacement, motion, force, mass, thermal and electromagnetic.
HISTORY
DR. O. WOLTER (founder of Nanosensors)
SIGNAL TRANSDUCTION
Convert a Chemical Binding Event into a Readable Signal.
ELECTRICAL DETECTION
Reading chemical
information
electronically .
ARRAYS OF ELECTRICALLY WIRED NANOSENSING ELEMENTS
OTHER TYPES
• Metal nano particle sensors.
• Quantum dot
• Nano Wired based
• Carbon nanotubes based
• Metal oxide sensors
APPLIATIONS
• Disease detection
• Early and accurate environment pollutant detection
• Defense against biological and chemical weapons.
• Food quality detection and control
• Gadgets
• Cars
WHY ONLY NANOSENSORS??
• They are much smaller than conventional sensors, so they could be placed on a small test strip of paper or other material.
• Nano materials improve the sensitivity and sppd of detection, and detect multiple targets due to their unique properties.

Written by United Press International These large numbers "may appear impressive but they hide the fact that the nanosensor market
will be highly fragmented," said Lawrence Gasman, a principal analyst for NanoMarkets, a nanotechnology analysis firm in Sterling, Va.
