In order to obtain detailed images and highly resolution from NanoImages applied to Biolabelling for Biodetection and Bioimaging generation it is need it to overcome the resolution limit of optical microscopes. The minimum distance (d) between two structural elements to be imaged as two objects instead of one is given by d= λ / (2NA), where λ is the wavelength of light and NA the numerical aperture of the objective lens. That in the optimal conditions, with white light the resolution of optical microscopes can arrive to 250 nm. This challenge was overcame by the last Nobel Prix in chemistry 2014 obtained by E. Betzig, S. W. Hell, W. E. Moerner by a switch on/off molecular Fluorescence. However, it still exists needs in enhanced fluorescence methodologies in the Nanoscale for Bioimaging applications and Lab-on particle applications for Single Molecule Detection (SMD). Within this field it is of our interest the Metal Enhanced Fluorescence (MEF) and Enhanced Plasmonics (EP) phenomena for NanoImaging and Ultraluminescent Bioimaging applications. In this context it was showed and discussed advances in Nanomaterial design for non-classical light generation.
