Professor Bahman Anvari and colleagues from the University of California, Riverside and the University of Maryland have developed nanoparticle systems with greater fluorescence emission when compared to known dyes. These nanoparticles incorporate dual near infrared fluorescence (NIR) and magnetic resonance (MR) dyes for improved fluorescence.  The nanoparticles encapsulate brominated carbocyanine dyes with MR qualities and ICG with NIR properties. This technology is advantageous because these nanoparticles containing these dyes exhibit greater fluorescence emission when compared to the individual dyes.  This presents a promising dual-mode platform with high optical sensitivity and clinical diagnostic and research applications.  

This technology provides methods for synthesizing a group of naturally occurring compounds, syrbactins, and their derivatives, being of significant commercial value due to the ability of some of the members to inhibit proteasomal activity. TIR-199, for example, is one of the most potent proteasome inhibitors synthesized so far. The efficacy and efficiency of this novel drug candidate in inducing tumor cell death in multiple myeloma, neuroblastoma, and other types of cancer (e.g. kidney, colon, melanoma, ovarian) has been demonstrated using in vitro systems, cell lines, and animal models (reported for the first time for a syrbactin compound). TIR-199 drug candidate is ready for further pre-clinical and eventually clinical studies.  

Professor Giulia Palermo and colleagues from the University of California, Riverside and the University of Rochester have developed high-fidelity Cas13a variants with increased sensitivity for base pair mismatches.The activation of these Cas13a variants can be inhibited with a single mismatch between guide-RNA and target-RNA, a property that can be used for the detection of SNPs associated with diseases or specific genotypic sequences.  

Professor Hideaki Tsutsui and colleagues from the University of California, Riverside have developed a portable handheld device for nucleic acid extraction. With its high-speed motor, knurled lysis chamber for rapid sample lysis, and quick nucleic acid extraction using paper disks, this device can yield ready-to-use extracts in just 12 minutes, significantly reducing the time required for sample preparation. This technology is advantageous over current methods as it can be expedited without the need for cumbersome specimen collection, packaging, and submission, shortening the turnaround time.
