The emergence of Covid-19 and Other Infectious Diseases to Boost Demand For Microplate Readers

A microplate reader is a multifunctional instrument used for the measurement of many physical and chemical reactions in a microplate. In addition to biochemical, biological, and pharmacological research, both at professional and academic levels, plate readers are also being used in the food and cosmetic industry, environmental research, and even in the medical field. The cost of the readers range starts at 2.500 Euro for a simple filter-based ELISA microplate reader and could go up to over 100.000 Euro for a high-end in Germany.

One such way of measuring the amount of friction is through the method of passive adsorption. In passive adsorption, the current passing through microplate readers is measured as a change in resistance as a result of the presence of certain molecules. The most common substances studied are amino acids, lipids, fatty acids, glycerol, cholesterol, and protein. There are different types of microplate models available for passive adsorption; the most common of which are the thermal microplate, the chemical microplate, and the magnetic microplate.


The emergence of Covid-19 boosts the demand for microplate readers. Microplate readers are specialized instruments that are used to measure light intensity on a sample of a material such as cells, viruses, and bacteria. In Germany, from 3 January 2020 to 10:37 am CEST, 9 August 2021, there have been 3,790,766 confirmed cases of COVID-19 with 91,782 deaths, reported to WHO. As of 31 July 2021, a total of 92,425,426 vaccine doses have been administered.


Microplate readers can measure the amount of a particular substance based on a signal generated from a variety of sensors that are built into the device. Some microplate readers have a molecular probe attached to the surface of the plates. This probe allows the reader to focus its electromagnetic field on the substance. Depending on the type of material being tested, the signal generated varies. However, most microplate readers make use of a dual-mode sensor that first displays a lower level of the signal and then a higher one based on the frequency of the movement of the sample molecules through the sample area.


The third type of microplate reader utilizes an excitation method where the kinetic energy of molecules in solution causes them to vibrate, thus creating an electric field that is detected by the sensor. When the two modes of sensing are combined, the result is the ability to measure very low levels of signal strengths and high signal sensitivity. These types of devices have been used for various applications in scientific testing and experimental analysis.

Microplate readers measure properties based on physical differences between the plates and their electrically charged counterparts. This difference in capacitance and electrical field affects the amount of charge carried by the substance as it passes through the microplate. The amount of charge that is absorbed by the material is denoted by the ratio between the charge carriers measured in a particular area and the total charge carried by the sample over a large area. This method of measurement is commonly used in the field of electronics, where electronics properties are physically measurable.


Microplate readers can be used to determine resistivity, density, homogeneity, homogenous conductivity, specific gravity, quantitative conductivity, electrical conductivity, thermal conductivity, and electrical discharges. In the process of measurement, the results of the assays are interpreted in terms of geometric analogs using the theory of electromagnetic induction. Different assays use different techniques to determine the properties.
