ROS-Responsive Nanoparticle Drug Release in Wound Inflammation

Interactive 3D reaction-diffusion simulator: reactive-oxygen-species (ROS) produced by a wound's inflammatory core diffuses through the tissue and triggers Hill-kinetics degradation of ROS-responsive nanoparticles, releasing their drug payload exactly where inflammation is highest.

This simulator models a stimuli-responsive drug-delivery strategy used in advanced wound dressings: nanoparticles whose polymer shell degrades in response to reactive oxygen species (ROS), the elevated-inflammation signal produced by immune cells in a poorly-healing wound. A 2D reaction-diffusion field represents ROS spreading and decaying across the wound bed from an inflamed core, while several hundred instanced nanoparticles sample the local ROS concentration beneath them and degrade with saturating Hill kinetics, releasing their drug payload preferentially where inflammation is worst. Adjust inflammation intensity, ROS diffusion range, nanoparticle ROS-sensitivity and dose to see how the release profile and its spatial selectivity change, with live readouts for cumulative drug released, peak ROS concentration and the fraction of particles fully triggered.
