Protein Corona Formation — Vroman Effect Simulator

Drop a nanoparticle into simulated blood plasma and watch abundant proteins slap onto its surface first, forming a fast soft corona, then watch rarer high-affinity opsonins slowly displace them into a hard corona — the Vroman effect that decides whether the immune system clears the particle or lets it reach its target.

ControlsTime acceleration sets how fast plasma exposure elapses; Opsonin-rich plasma slider shifts protein abundance toward inflammatory-state ratios; PEGylation slider suppresses all binding/displacement rates equally; Play/Pause and Reset control the run; the scrub slider inspects the recorded corona-composition timeline at any past instant, with a Live button to resume following the running simulation.

The instant a nanoparticle enters blood plasma, proteins adsorb onto its surface — not the engineered coating, but this "corona" is what cells and the immune system actually recognize. Abundant proteins bind first and fast, forming a soft corona; over time, rarer but higher-affinity proteins slowly displace them, forming a hard corona that determines whether the particle is cleared or reaches its target. Tune plasma composition, PEGylation and time acceleration to watch the exchange play out.
