Porous Cellulose Acetate/Block Copolymer Membranes for the Recovery of Polyphenolic Compounds from Aquatic Environments
Phenethyltrimethoxysilane (P0113) Polyphenolic and other phenyl containing compounds have long had wide-spread applications in the chemical industries. In addition, these chemicals are synthesized by plants, so they are also naturally occurring, not just synthetically made. With their high prevalence, many phenolic based compounds end up in runoffs from urban, agricultural, and industrial sources and end…
UCT Dispersive SPE Sorbent Cited in Anticoagulant Rodenticides Article
In a new paper by Lori Smith et al, published in the Journal of Food and Agricultural Chemistry (DOI: 10.1021/acs.jafc.7b02280), a wide and diverse range of anticoagulant rodenticides (ARs) were analyzed in rodent liver samples using UCT’s dispersive SPE (d-SPE) tubes for sample clean-up. ARs are used to control rodent populations, acting as vitamin K antagonists by inhibiting vitamin K epoxide reductase. Consequently, formation of prothrombin and related blood-clotting factors (VII, IX and X) are blocked, causing massive hemorrhage and mortality.
The shape of pleomorphic virions determines resistance to cell-entry pressure
The study of viruses is a never-ending battle. Even for well-studied viruses such as the influenza A virus, scientists are continuing to discover new data. A research group in Brandeis University has begun to study the particle structure of viruses to determine how the shape influences infectivity. This study used fluorescently labeled microscope slides, functionalized…
High-Resolution Optical Tweezers Combined with Multicolor Single-Molecule Microscopy
Optical tweezers (OT) are a device that can manipulate individual molecules with cells by using light from low-wattage lasers and are used to study and manipulate DNA and RNA. There is a serious limitation to these optical tweezers. They can only measure a single degree of freedom, which is then projected onto a single dimension….
UCT Flagship Sorbent Cited in Khat Analysis Study
In a recent study authored by Ibraheem M. Attafi et al., published in the Arab Journal of Forensic Sciences & Forensic Medicine ((2018) 7(1) 922-930)), a postmortem case report aimed to identify and determine the concentration of cathine and cathinone in different body organs and green chewed plants found in the mouth of the deceased. Extraction of the khat compounds was performed using UCT’s Clean Screen® DAU in conjunction with LC-MS/MS quantitative analysis to confirm that samples were positive for cathinone and cathine.
A Circular Gradient-Width Crossflow Microfluidic Platform for High-Efficiency Blood Plasma Separation
Clinical diagnostic tests use blood plasma for detecting the biomarkers of illnesses such as diabetes, cancer, and many others. Blood plasma makes up about half of the make up of whole blood and the separation of plasma is both labor and time intensive. A group of researchers from Texas A&M University have designed a microfluidic…
