Abstract
A method and device for detecting fluorescent biological molecules and/or microorganisms containing said fluorescent biological molecules within a given area or space. The method comprises illuminating an area or space with light of a suitable wavelength to excite the fluorescent biological molecules and then measuring the resultant fluorescent light from the illuminated area or space at a wavelength indicative of fluorescence of the fluorescent biological molecules. The invention can also be used to detect changes in the levels of such biological molecules and/or microorganisms within a given area or space by illuminating the area or space at two different times, measuring the resultant fluorescence after each illumination and comparing the respective fluorescence measurements. The present invention is also directed to a hand-held device for in vivo inspection of desired areas or spaces.
