Physicochemical Properties Predict Retention of Antibiotics in Water-in-Oil Droplets
The ability to study antibiotic resistant pathogens by using methods such as antimicrobial susceptibility testing (AST) is important, especially with the rapid emergence of more and more antibiotic resistant pathogens. AST is a method with uses droplets of solutions as individual, isolated environments, thus allowing for high-throughput experiments. The ability for small molecule antibiotics to…
Magnetically-Actuated Microposts Stimulate Axon Growth
New research published in the Biophysical Journal introduces a new method utilizing magnetically-actuated microposts as a scaffold for the stimulation of axon regeneration. These non-toxic, magnetic microposts, synthesized using tridecafluorooctyltrichlorosilane (United Chemical Technologies PART # T2492) as a mold release agent, were used as scaffolds for neuron growth and support for application of a magnetic field over…
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.
UCT Silane Cited in Droplet-Based Microfluidic Article
The kidneys are considered critical for the long-term control of blood pressure by regulation of body fluid and blood volume. In support of this concept, the kidneys control the systemic activity of the pro-hypertensive renin-angiotensin-aldosterone system by regulating the production and release of renin from juxtaglomerular cells. The relationship between the endocannabinoid system in the…

UCT’s Flagship Sorbent (ZSDAU020) cited in Remifentanil article
UCT is recognized for its support for the forensic toxicology community not only domestically, but abroad. This is demonstrated in a new article published in the journal Toxicologie Analytique & Clinique authored by Dr.J Long et al.,(http://dx.doi.org/10.1016/j.toxac.2016.11.003 2352-0078). In this paper, the authors utilize UCT’s famous Clean Screen ® DAU solid phase extraction column (ZSDAU020) to extract remifentanil, a short acting fentanyl analogue, from post mortem blood samples. This is believed to be the first report of a concentration of remifentanil in postmortem blood.
