Protein Corona 2D: PEG Brush vs Opsonin Adsorption on a Transplant Surface

Interactive 2D cross-section simulator of protein-corona formation on a transplanted organ surface: watch plasma opsonins diffuse toward a PEGylated nanocoating, get repelled by steric brush pressure, and trigger macrophage recognition once opsonin coverage crosses threshold.

The moment a transplanted organ or implant meets blood, plasma proteins begin adsorbing onto its surface, forming a "corona" that the immune system reads to decide friend or foe. This 2D cross-section simulator renders that race in real time: plasma opsonin particles diffuse via Brownian motion toward a nanocoated organ surface, and a PEG brush layer of tunable grafting density exponentially suppresses their odds of sticking on each collision. Turn the coating density down and the surface floods with adsorbed protein until a macrophage sentinel docks and rejection begins; turn it up and the surface stays immunologically invisible far longer, exactly the effect PEGylated and zwitterionic "stealth" coatings are engineered to produce on real vascular grafts and encapsulation devices. An optional live coverage-vs-time graph and drag-to-rotate cross-section view let you inspect the kinetics from any angle.
