Abstract
The computer screen photo-assisted technique (CSPT) exploit computer screens as a controlled light source and web cameras as imaging detectors. When used in combination with a disposable micro structured substrate, we demonstrate the fluorescent fingerprinting of 100μm elements packed at 46 elements/mm2. The micro structures aid the fluorescent detection by breaking the substrate confinement of the fluorescence indicators emission while separating the emitted signal from the excitation. Due to this efficient separation of light it is possible for the web camera, in zoom mode, to separate individual lOOum structures compatible with high density response pattern generation, using a standard CSPT configuration. ©2007 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
