Electron microscopy spraying technique

Butyl acrylate-methyl methacrylate copolymer latices with a core-shell structure were prepared by a sequential emulsion polymerisation technique. SEM and transmission electron microscopy studies undertaken on the polymer dispersions, powders obtained by spray drying and latices prepared by redispersing the powders in water revealed the influence of polymerisation parameters on the micromorphology of the starting latices, and correlations between the dimensional and micromorphological characteristics of the starting latices, the powders and the redispersed latices. 8 refs. 

Fig. 2.2 Structures and scanning electron microscopy (SEM) photographs of different MALDI matrices deposited onto a stainless steel plate. Lower SEM photographs show E. coli cells cocrystallized with different MALDI matriees (matrix applied with a spray deposition technique). Arrows point to intact cells within the erystalline matrix.

Dried spray deposits on leaf surfaces have been studied using scanning electron microscopy (SEM), while secondary electron emission, cathodoluminescence, and X-ray microanalysis have been used to examine the phytotoxic effects of pesticides or surfactants on the leaf epidermis. Using these techniques, it has been demonstrated that uptake continued after spray deposits have visibly dried. ...
