For this reason it is highly important to monitor the biomolecules present in the human body. While the most of carbon-containing molecules are organic compounds, there are a few exceptions. Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism’s genetic code —the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth. Among the different classes of biomaterials that could be biologically modified, synthetic polymers are especially interesting because their surfaces may contain reactive groups such as –OH, –COOH or NH2 groups, or they may be readily modified with other reactive groups such as azide, alkyne, and SH groups. For surfaces of metals, metal oxides, inorganic glasses or ceramics, biological functionality can sometimes be added via a chemically immobilized or physically adsorbed polymeric or surfactant adlayer, or by use of techniques such as plasma gas discharge, corona discharge in air or ozone to modify polymer surface compositions with functional groups (see also Chapter I.2.12). The electrochemical sensing of Cu2 + ion is possible by the following redox reaction. Hello Friends, My name is Sanjay Bhandari. Any changes in the concentration of specific biomolecules may lead to the malfunction of the cells and organisms. A 24-year-old Swiss chemist, F. Miescher, who worked in Germany in 1868, extracted what was then called “nuclear material” from a patient’s wound pus cells. Common biological macromolecules include proteins, nucleic acids, and polysaccharides. Among various sensing strategies, the electrochemical sensing approach is more viable because of its portability, sensitivity, and selectivity compared to other methods. Enzyme reactions can be applied to detect smaller biomolecules such as hydrogen peroxide and glucose. and inorganic matter. Biomolecules are important not only because they fulfill vital functions of support, regulation and transport of the body of living beings, but because they integrate their bodies themselves, that is, our bodies are made of them. They not only have biological functions but also have large molecular weights and complex structures. To understand the underlying mechanism of the functions it is therefore essential to monitor the dynamic and kinetic behaviors of biomolecules under their normal working conditions. | Properties, uses, and Tests, How to test for Formaldehyde?
