PLASMON-ASSISTED VISIBLE LIGHT EMISSION IN THE INTERACTION OF HIGHLY CHARGED IONS WITH SURFACES

The measurements of spectra with wavelengths from 200nm to 1000nm emitted from solid surfaces excited by highly charged ions(HCIs) are reported. The results show that the spectral line of specimen materials can be excited by HCIs, and when the quantity of electric charge is more than a critical number, the intensity of the excited spectral line will be sharply enhanced. Theoretical analysis gives that, this mutation is tied up with the excitation of the conducting-electron gas plasmon in the metal surface.

Specific Labelling

In scanning luminescence x-ray microscopy (SLXM), a high resolution x-ray probe is used to excite visible light emission (see Figs. 1 and 2). The technique has been developed with a goal of localizing dye-tagged biochemically active sites and structures at 50 nm resolution in thick, hydrated biological specimens. Following our initial efforts, Moronne et al. have begun to develop probes based on biotinylated terbium; we report here our progress towards using microspheres for tagging.Our initial experiments with microspheres were based on commercially-available carboxyl latex spheres which emitted ~ 5 visible light photons per x-ray absorbed, and which showed good resistance to bleaching under x-ray irradiation. Other work (such as that by Guo et al.) has shown that such spheres can be used for a variety of specific labelling applications. Our first efforts have been aimed at labelling ƒ actin in Chinese hamster ovarian (CHO) cells. By using a detergent/fixative protocol to load spheres into cells with permeabilized membranes and preserved morphology, we have succeeded in using commercial dye-loaded, spreptavidin-coated 0.03μm polystyrene spheres linked to biotin phalloidon to label f actin (see Fig. 3).
