Emerging Technology

Moxtek has achieved low cost, wafer-scale manufacturing of photonic crystal, plasmonic and other hybrid structures. Here the application of TiO2 photonic crystal guided-mode resonance structures for label-free sensing and microarray based surface enhanced fluorescence based detection is presented. The structures exhibited an average 7.7 fold fluorescence enhancement over a reference glass slide for Human IgG, IgM, IgA, and streptavidin-biotin assays and also exhibited a 2.5nm spectral shift following the attachment of a self-assembled monolayer, thereby exhibiting the capability for detecting sub-monolayers thicknesses.

Emerging Technology

Moxtek has developed cost effective and reliable methods to obtain uniform wafer scale metallic nanohole array patterned biochips. Here their use as fluorescence enhancing substrates for Cy3 based protein microarrays is demonstrated. The structures, utilizing highly focused and enhanced optical fields, greatly boost the fluorescence SNR, allowing for the detection of antigen concentrations 3+ orders of magnitude lower than current commercial standards.
