CoreSpin: Creating Better Heat Exchangers – One Protein at a Time

  • Story
  • Design
  • Manufacturing Insights

Blending biology with engineering, CoreSpin is developing a spider-silk–based coating that binds to copper, prevents biofouling, and restores heat exchanger efficiency. By applying a monolayer of engineered spider silk protein to copper surfaces, this solution reduces energy loss in air-cooling systems like HVAC units and data centers while maintaining optimal heat conductivity.
