ABSTRACT
Biomicroelectromechanical systems devices deal with biomolecular species from the molecular level to the cellular level. The biological activity of proteins is determined by the properties of amino acids that constitute protein composition. From an engineering point of view, the hydrophilic or hydrophobic characteristics of different amino acids are of paramount importance for understanding the adsorption of proteins onto solid surfaces. Proteins are large biological molecules made of amino acids linked into linear chains by peptide bonds. The structures built from two to one hundred amino acids are usually called polypeptides, while longer polypeptide structures are called proteins. The naturally occurring fats, oils, and waxes are all esters formed between long-chain fatty acids and glycerol. Lipoproteins are complex aggregates of lipids and proteins that make the lipids compatible with the aqueous environment of body fluids and enable their transport throughout the body of all vertebrates and insects.
