Small particles of indium or silver were encapsulated in a thin polymer film matrix by simultaneous plasma polymerization and metal evaporation. Electron-beam irradiation inside transmission electron microscopes and with a microfocus electron source was used to induce changes of the encapsulated particle size and shape. At encapsulated indium particles, substantial microstructural changes were observed during the electron-beam irradiation in the electron microscope. Selected area diffraction demonstrates that indium oxide was formed during the electron irradiation. Additional in situ annealing demonstrates that the indium melting point was not reached during electron-beam-induced local heating of the indium particles. At electron-beam irradiation of plasma polymer films with encapsulated silver particles by using a microfocus electron source, the coalescence of the silver particles can be limited to the irradiated areas of the films.

One goal in electron microscopy of biological specimens is to improve the quality of data to equal the resolution capabilities of modem transmission electron microscopes. Radiation damage and beam- induced movement caused by charging of the sample, low image contrast at high resolution, and sensitivity to external vibration and drift in side entry specimen holders limit the effective resolution one can achieve. Several methods have been developed to address these limitations: cryomethods are widely employed to preserve and stabilize specimens against some of the adverse effects of the vacuum and electron beam irradiation, spot-scan imaging reduces charging and associated beam-induced movement, and energy-filtered imaging removes the “fog” caused by inelastic scattering of electrons which is particularly pronounced in thick specimens.Although most cryoholders can easily achieve a 3.4Å resolution specification, information perpendicular to the goniometer axis may be degraded due to vibration. Absolute drift after mechanical and thermal equilibration as well as drift after movement of a holder may cause loss of resolution in any direction.
