A bioassay is a biochemical test to estimate the potency of a sample compound. Usually this potency can only be measured relative to a standard compound. [3] [1] A typical bioassay involves a stimulus (ex. drugs) applied to a subject (ex. animals, tissues, plants). The corresponding response (ex. death) of the subject is thereby triggered and ...
A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.
A clinical chemistry analyzer; hand shows size. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments. [1]
Biosensors could be used to monitor air, water, and soil pollutants such as pesticides, potentially carcinogenic, mutagenic, and/or toxic substances and endocrine disrupting chemicals. [101] [102] For example, bionanotechnologists developed a viable biosensor, ROSALIND 2.0, that can detect levels of diverse water pollutants. [103] [104]
Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. [1] The most common feature of the research in this subject is to seek an explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems.

They are regulated by concentration using environmental chemistry and chromatography laboratory testing. Nutrients leaching from agricultural land into water courses, which can lead to algal blooms and eutrophication. [8] Urban runoff of pollutants washing off impervious surfaces (roads, parking lots, and rooftops) during rain storms.
The 4 main classes of molecules in biochemistry (often called biomolecules) are carbohydrates, lipids, proteins, and nucleic acids. [35] Many biological molecules are polymers: in this terminology, monomers are relatively small macromolecules that are linked together to create large macromolecules known as polymers.
Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
