Polymeric autofluorescence

Other material parameters that are critical to the successful application of microfluidic devices include autofluorescence (when optical detection is used), permeability (when living cells are used), chemical resistance (when nonaqueous solutions are used), and analyte adsorption. Table 2 lists the chemical resistances of several common polymeric materials. Analyte adsorption is a parameter that is highly dependent on several material characteristics, including hydrophobicity and surface charge. The biocompatibility of many plastic materials is associated with both of these parameters and has been evaluated and characterized extensively in the biomedical engineering hterature. [Pg.890]

The fluorescence phenomenon is a severe drawback for the quantitative processing of spectroscopic data. In the case of polymeric membranes, their autofluorescence is known to decrease with the following treatments [21] ... [Pg.133]
