Wheatstone Bridge,urrent. We did not measure .. and .. separately and make a subtraction, as both are on a scale of several volts (measured in 0–20 V scale), while their difference is only in millivolts (measured in 0–200 mV scale). If you have a DMM, you can connect one of its leads to the position . and the other t

Op-Amp,r, strain gauge, and more. For practical applications, the voltage signals generated from these sensors must be conditioned and appropriately amplified. This task is usually achieved by an ., more commonly referred to as an .-., which we briefly used in Chap. . laboratory.

Light Sensors,rs. They are also becoming very important in many biosensor applications, commonly used in conjunction with fluorescent dyes. In this chapter we will examine a group of light sensors that are made out of semiconductors, namely photoresistor, photodiode (PD), and phototransistor. Light sensors are ty

Spectrophotometry,nsitive to a certain range of colors, e.g., UV-blue, red-IR, etc., they cannot tell the exact color or color combination of a light signal. Photodiodes (and most other optoelectronic light sensors) simply inform us of the intensity of light signals. Detailed information on color combination can be o

Fluorescence,wavelength. This method works well for a variety of applications. Despite its popularity, it has some limitations. The target molecule must exhibit specific coloration(s), i.e., absorption peaks at certain specific wavelength(s). It is possible to use a combination of an enzyme and a substrate that

Lab-on-a-Chip Biosensors,ps that are labor-intensive and require a skilled operator. In fact, there have been attempts to provide a higher level of automation and to increase ease of use for immunosensors (and certainly other biosensors as well), through fabricating more complicated microchannels. These attempts have usuall
