integrating man-made nanoparticles with natural cellular membranes Arytha Biosciences, LLC is a nanotechnology-driven and research-focused biotech company based in San Diego, California. We develop therapeutics using nanoscale particles (around 100 nm or smaller) that mimic the properties and functions of living cells and organisms. Our business goal is to translate biomimetic nanoparticles into medical applications to improve healthcare. Arytha Biosciences, LLC uses natural cell membranes to camouflage man-made nanoparticles. The resulting “cell membrane-coated nanoparticles” combine advantages of both materials. This biomimetic platform presents various innovative therapeutic strategies.
