MICROSCOPIC SENSOR [3 records]

Record 1 2011-12-14

English

Subject field(s)
  • Analytical Chemistry
  • Biotechnology
CONT

As with larger optical sensors, optical nanosensors can generally be classified into one of two different classes : 1) chemical nanosensors, or 2) nanobiosensors, depending on the type of recognition element(i. e., chemical or biochemical) used to provide specificity to the sensor. Although both of these classes of optical nanosensors are capable of obtaining quantitative measurements in many different microscopic environments, they have found an ideal application in the analysis of chemical and biochemical species present within living cells. Their small sizes allow them to be inserted and precisely positioned within individual cells to obtain spatially localized measurements of chemical species in real time.

CONT

Basé à [à un centre de recherche], il a pour but de développer des nanocapteurs chimiques et biologiques, à travers trois sujets de recherche : le développement d'outils pour la fabrication de motifs à l'échelle nano, les phénomènes de reconnaissance biologique (acides nucléiques et protéines) et chimique (petites molécules) sur une surface, et les transmissions des signaux, optiques ou électriques, qui en découlent.

Record 2 2006-11-23

English

Subject field(s)
  • Semiconductors (Electronics)
  • Video Technology
DEF

A derivative of the HAD [hole accumulated diode] sensor that incorporates microscopic lenses mounted over each sensing pixel.

OBS

Hyper HAD sensors have no perceptible smear and are nearly twice as sensitive as HAD sensors.

French

Domaine(s)
  • Semi-conducteurs (Électronique)
  • Vidéotechnique
DEF

Dispositif à transfert de charge dérivé de la technologie des capteurs HAD (hole accumulated device) qui intègre une structure optique spécifique au niveau de chaque pixel.

OBS

Les capteurs Super HAD CCD ne présentent aucun phénomène perceptible de bavure et ils sont dotés d'une sensibilité presque deux fois supérieure à celle des capteurs HAD.

Record 3 1993-07-22

English

Subject field(s)
  • Information Processing (Informatics)
DEF

A tiny dot of heat that can be used with other pixels to create an image, the way the TV does.

OBS

A recent invention of A. Parameshwaran(Simon Fraser Univ.), an expert in nanotechnology who has also built a miniature pressure sensor, and a microscopic scale that can weigh a single living cell in nanograms. The thermal pixel has already been licensed by a US company.(Financial Times of Canada, 10 March, 1993, p. 10).

French

Domaine(s)
  • Traitement de l'information (Informatique)
OBS

Par analogie à "image thermique", "configuration thermique", "détecteur thermique", "point thermique", "traceur thermique" et "thermoplastique".
