Applications, microscopy membranes

Total Internal Reflection Fluorescence Microscopy (TIRFM) is another useful tool for studying the reactions of individual molecules adsorbed, adhered or bound to surfaces. Typical applications are membrane fusion of vesicles [177], conformational and orientation changes [178] and lateral mobility of molecules [179],... 

Ultrafiltration utilizes membrane filters with small pore sizes ranging from O.OlS t to in order to collect small particles, to separate small particle sizes, or to obtain particle-free solutions for a variety of applications. Membrane filters are characterized by a smallness and uniformity of pore size difficult to achieve with cellulosic filters. They are further characterized by thinness, strength, flexibility, low absorption and adsorption, and a flat surface texture. These properties are useful for a variety of analytical procedures. In the analytical laboratory, ultrafiltration is especially useful for gravimetric analysis, optical microscopy, and X-ray fluorescence studies.

In this chapter we report recent analytical applications of CL imaging for the detection of biospecific reactions in macrosamples such as microtiter plates of different format (96 or 384 wells), filter membranes and irregular surfaces represented by specimens related to the cultural heritage, and results obtained when the CCD detector is coupled with optical microscopy for enzyme localization, immunohistochemical reactions, and complementary DNA (cDNA) detection (Table 1).

CARS microscopy has emerged as a highly sensitive analytical tool for vibrational bioimaging, predominantly, of lipids in membrane model systems [69, 81-84], live unstained cells [85-95, 43], and both ex vivo and in vivo tissues [26, 96-103, 43]. Examples of CARS imaging applications in the physical and material sciences include the study of fracture dynamics in drying silica nanoparticle suspensions [104], patterned polymeric photoresist film [105], drug molecules in a polymer matrix [106], and liquid crystals [107, 108],...

Conventionally, wide-field Raman microprobes are applied for such mappings, but, recently, confocal microscope systems have also been used (Bridges et al., 2004 Puppels et al., 1990, 1991 Schliicker et al., 2003). Confocal microscopy originated from biological applications with the goal of analysis of the insides of cells without destruction of the cell membrane. Confocal microscopy selectively rejects any information from planes closer or further from the focal plane. Confocal microscopy is a...
