Diagnostic Professionals

A Few Words About Us
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).

Mark Sternberg

CFO & Nanomaterial Specialist

Mr. Mark Sternberg MBA: Mr. Sternberg serves as DDI CFO (Chief Financial Officer) has a long-standing experience in industrial nanoparticles applications over 25 years. Mr. Sternberg’s experience commenced from the production of thin film coatings using sub-micron and nanoparticles which are then coated onto polyester films. Mr. Sternberg was a co-inventor on several patents for polishing applicaitons. Additionally, Mr. Sternberg has broad experience in development of industrial application of nanodiamond particles, as he was one of the founders of a company who first brought the detonated nanodiamond particles to production in the United States. Detonation of nanodiamond is part of the process, however, there are cleaning and functionalization steps too, for which Mr. Sternberg has many years of experience.
