Bio-engineering of functional fluorescent nanodiamond particles for Lateral Flow Assays (Covid-19, other infectious diseases); Targeted drug delivery devices for the detection and treatment of blood clots and cancerous tumors. Debina Diagnostic’s core technology is based on novel Fluorescent NanoDiamond particles engineered (physically) to emit strong Near Infra-Red (NIR) light upon exposure to specific Laser light (F-NDP). DDI affiliated laboratories specialize in Bio-Engineering of the F-NDP by additives linked to the particles that enable homing of the particles on targets of interest such as infectious pathogens (viruses, bacteria, toxins) and pathological loci in human body (such as blood clots, vascular plaques, tumors etc).
