Founded in 1986 in Horsham, PA, United Chemical Technologies, Inc. (UCT, Inc.) has grown from a manufacturer of solid phase extraction sorbents into a major competitor in the fields of specialty chemicals, chromatographic media and sample preparation products. UCT began with a novel technological idea for solid phase extraction (SPE): bond two different functional groups to a solid support material in order to create phases that are capable of extracting samples based on different chemical principles. The first product was our CLEAN SCREEN® DAU. This product incorporated an ion exchange functionality with a hydrophobic alkyl chain. This product was quickly adopted in analytical labs and is now the most widely used SPE material in the clinical and forensic industry for the clean extraction of biological matrices.
UCT Silane Cited in Plasmon Research Study
Ultrasensitive and selective detection and quantification of dopamine (DA) plays a key role in monitoring neurodegenerative diseases and the detection limit reported is typically in the lower nanomolar range. Pushing the detection limit to picomolar (pM) or lower for this particular target to cover the physiological levels (< 130 pM) is significant. In the following article, DA DNA aptamer (DAAPT) gold nanoparticle (AuNP) conjugate is utilized to enhance the surface plasmon resonance (SPR) signal, which enables to detect and quantify DA in the femtomolar (200 fM) to pM range.
