Abstract: The present disclosure concerns a sensor for detecting a sample analyte having an oxidizable phenolic group suspected to be present in a sample. The sensor comprises a sensing electrode, a plurality of sensor analytes associated with the sensing electrode, optionally a baseline electrode, and a sample receiving region in fluid communication with the sensing electrode. The sensor analyte, before its association with the sensing electrode, is the same chemical species as the sample analyte.

Abstract: Nanozymes capped with a radical-scavenging capping agent are disclosed for use in biosensing assays with improved sensitivity. The radical-scavenging capping agent facilitates the capture and retention of one or more radicals for enhancing a catalytic reaction. In some example embodiments, the nanozyme capped by the radical-scavenging capping agent is capable of catalyzing the decomposition of hydrogen peroxide or molecular oxygen. The capped nanozymes may be incorporated with an electrode, such as the working electrode of an electrochemical sensor, for achieving enhanced catalytic activity and a lower limit of detection. In some example embodiments, the radical-scavenging capping agent is or includes thiocyanate.

Abstract: The present invention relates to a novel solvent-free process for the production of protein-, starch- and fiber-enriched fractions or fractions rich in specific compounds from pulses, grains, oilseeds, and dried fruits. Unlike conventional wet processes, this dry process preserves the natural configuration and structure of separated components. This process employs a tribo-electrostatic technique to selectively charge proteins, carbohydrates, fibers, and other components in pulses, grains, oilseeds, and dried fruits and separates them based on the magnitude and type of their charge.
