Many different methods have been developed in recent years to gain insight into the structure of proteins membranes organelles and cells.
A fundamental principle in diffraction limited optical microscopy requires that the spatial resolution of an image is limited by the wavelength of the incident light and by the numerical apertures of the condenser and objective lens systems.
Presents several biological applications of near field optical microscopy in combination with force microscopy.
Probes and distance control.
Near field scanning optical microscopy provides a technique for examining specimens with ultra high spatial optical resolution that greatly expands the analytical toolbox of the microscopist.
