UV patternable high refractive index inorganic–organic hybrid materials prepared by sol–gel process can be nanoimprinted in order to get photonic crystal nanopatterns. Non-hydrolytic sol–gel process can make a UV curable and relatively high refractive index hybrid material, which can be cured without a significant shrinkage for nanoimprinting. Sol–gel process of heterogeneously functionalized s...

A conductometric urea biosensor based on sol–gel-immobilized urease on a screen-printed inter-digitated array (IDA) electrode has been developed. The screen-printed thick-film IDA electrode has proven to be an excellent conductometric transducer in which the admittance signal was dominated by the conductance signal and the resulting dynamic range was wide enough to be employed for the construct...

Valerie Rapson Greece Olympia High School Advisor: Kenneth L. Marshall University of Rochester Laboratory for Laser Energetics Summer High School Research Program 2005 1. Abstract Sol-gel coatings are used on the OMEGA laser optics as anti-reflection (AR) coatings to maximize their transmittance. Over time, trace organic compounds in the laser bay contaminate these sol-gel coatings, reducing th...

Active protein micropatterns and microarrays made by selective localization are popular candidates for medical diagnostics, such as biosensors, bioMEMS, and basic protein studies. In this paper, we present a simple fabrication process of thick (approximately 20 microm) protein micropatterning using capillary force lithography with bifunctional sol-gel hybrid materials. Because bifunctional sol-...

A wide variety of enhanced and modified sol-gel bulk and thin film processes for the development of sensors and biosensors have been witnessed in the last two decades. The porous silica glass material prepared by the sol-gel process is a promising host matrix for the encapsulation of various biomolecules viz. proteins, antibodies, enzymes. The entrapped biomolecules have shown to retain their f...
