Instant NanoBiosensors - Antibody Characterization Services - Brochure

Our biosensing platform takes advantages of the technologies of fiber optic particle plasmon resonance (FOPPR™) and microfluidic chip to achieve a label-free and ultrasensitive detection of analyte up to 5 orders of linear range within a few minutes. After coating gold nanoparticles (AuNPs) onto an unclad segment of an optical fiber, antibodies can then be immobilized onto the surface of AuNPs. Total internal reflection (TIR) occurs as light propagates along the fiber.
