(MENAFN- EIN Presswire) OpsisDxTM has the potential to detect signals in multiple types of cancer through a urine sample and can complement other early detection platforms. We are excited about the vast market opportunity.” - George Huang, Ph.D., Chief Financial Officer of Entopsis Inc. MIAMI, FLORIDA, USA, December 9, 2022 /einpresswire.com / -- The novel scientific concept behind opsisdx TM, developed by Entopsis Inc., is outlined in a recently published peer-reviewed scientific manuscript in the Royal Society of Chemistry Analyst journal. In addition, OpsisDxTM was selected by the editors of the journal to be featured on the journal's cover.
The manuscript, entitled 'A colorimetric chemical tongue detects and distinguishes between multiple analytes', demonstrates how photoinitiators can be used to profile simple and complex chemical mixtures using an array of polymers with distinct binding properties. The research team showed that photoinitiators have a newly discovered property. Once cleaved by ultraviolet (UV) light, the cleaved species remains in the polymer, and if the polymer happens to bind a substance, heating the polymer will cause a reaction between that substance and the cleaved species, resulting in color changes within the polymer. Applying heat is all that is needed to produce these color changes, hence allowing for polymer bound analytes to be detected quickly and simply.
“Think of when a dentist shines a blue light on a composite filling. That light acts on a photoinitiator within the filling, causing the material to polymerize and harden. This work demonstrates that these everyday photoinitiators have a second secret superpower; they can also react with analytes to produce colored signals” said Ian Cheong Ph.D., co-senior author and scientific adviser to Entopsis Inc.
The research team went on to show how a polymer array could be used to bind to analytes and create different color profiles based on the nature of the analytes. Each spot on the 70-spot polymer array, had unique physiochemical binding properties, where a given spot bound to each analyte with varying affinities. For example, one spot preferentially bound large, circular, positively charged water-loving molecules, while yet another spot prefered small, water-repelling molecules. Thus, exposing the array to a liquid sample produced a colorimetric readout based on the extent to which analytes bound to specific spots, and what colors were produced when the analytes and the cleaved species in the spot reacted upon heating.
This type of profiling allowed the Entopsis team to correctly distinguish between analytes, many with almost identical chemical compositions, with ~98% accuracy. The team is already working on applying this technology in combination with machine learning to detect early-stage cancers from urine samples and various research applications. If successful, this approach will serve as a multi-disease detection platform that may rival blood-based liquid biopsy tests.
