Patent number: 11125753Abstract: A system detects an analyte suspected of being present in a sample. The reader reads an optical tag on a substrate, which is configured to immobilize the tag on a substrate surface. The optical tag is bound to a probe and includes a plurality of pores that create an effective index of refraction. The plurality of pores and a thickness of the tag are selected for a reflectance property. The substrate is configured to contact a sample suspected of comprising an analyte. The probe is capable of binding specifically to the analyte. The reader is configured to expose the tag to light to generate a sample spectral signature that is a function of the effective index of refraction, the thickness of the optical tag, and whether the analyte is coupled to the probe. The sample spectral signature is compared to a reference to detect the analyte in the sample.Type: GrantFiled: March 23, 2018Date of Patent: September 21, 2021Assignee: TruTag Technologies, Inc.Inventors: Hod Finkelstein, Timothy Learmonth
