Matrix-assisted laser desorption/ionization — MALDI TOF mass spectrometer Matrix assisted laser desorption/ionization (MALDI) is a soft ionization technique used in mass spectrometry, allowing the analysis of biomolecules (biopolymers such as DNA, proteins, peptides and sugars) and large… … Wikipedia
Matrix isolation — Diagram representing a triangular, guest species (in red) isolated in solid host matrix (in blue). Matrix isolation is an experimental technique used in chemistry and physics which generally involves a material being trapped within an unreactive… … Wikipedia
Matrix (mathematics) — Specific elements of a matrix are often denoted by a variable with two subscripts. For instance, a2,1 represents the element at the second row and first column of a matrix A. In mathematics, a matrix (plural matrices, or less commonly matrixes)… … Wikipedia
Matrix (chemical analysis) — In chemical analysis, matrix refers to the components of a sample other than the analyte.[1] The matrix can have a considerable effect on the way the analysis is conducted and the quality of the results obtained; such effects are called matrix… … Wikipedia
Matrix-assisted laser desorption electrospray ionization — Schematic of a typical MALDESI setup Matrix assisted laser desorption electrospray ionization (MALDESI) is a method for creating ions that can be used for chemical analysis in a mass spectrometer.[1] It is related to desorption electrospray… … Wikipedia
Chemistry of biofilm prevention — Biofilm formation occurs when free floating microorganisms attach themselves to a surface. They secrete extracellular polymers that provide a structural matrix and facilitate adhesion. Because biofilms protect the bacteria, they are often more… … Wikipedia
