LSPR nanochips

are composed of the array of randomly distributed nanostructures of gold or silver on the glass substrate that supports Localized Surface Plasmon Resonance (LSPR) excitation at different light wavelengths in the visible spectral region. Similarly to SPR slides, it can be used for study of biomolecules and biomolecular interactions. However, measurements with LSPR nanochips are performed in the light wavelength scan spectral mode, which is an advantage in comparison to SPR slides. Like SPR slides, LSPR nanochip can be used for studies of both optical parameters of thin films of different materials deposited on its surface and kinetics of processes in investigated films in time and, if necessary, under external (applied potential, light irradiation) influence. Plasmonic nanochips can also be used for surface enhanced spectroscopy, e.g. enhancement of fluorescence, SERS and SEIRA measurements, etc. LSPR nanochips can be supplied in different sizes on pure glass or quartz substrates as well as with ITO conductive layer. Modification of Au surface with CH3, COOH, NH2 and SH functional groups is possible as an option.
Payment and delivery: University PO, wire and credit cards (via issue of an online invoice that can be paid by credit card). The order ships from Europe by regular post with tracking ($10, about 1-2 weeks) or by FedEx express ($35, 2-3 days).
