Latest Patents

Bibijana holds a patent titled "Detection of very low quantities of analyte bound to a solid phase." This patent describes a microscale binding assay, analyte binding array, and kits that utilize the mass action law to extract analytes from liquid samples. The technology involves the fabrication of sorbent zones that possess up to ten times the binding capacity per unit area compared to traditional polystyrene microtiter plates. The resulting arrays effectively deplete the liquid solution of analytes during incubation, allowing the assays to respond to the total mass of analyte in the sample rather than just the concentration. This method, combined with direct fluorescence detection in the near-infrared (NIR) spectrum, maximizes signal intensity while minimizing background noise, thereby enhancing sensitivity.
