Article Synopsis
- Colloidal colorimetric microsensors are developed to detect mechanical strains in materials, which could enhance their use in biosensing and chemical sensing applications.
- The sensors are made by assembling polymer-grafted gold nanoparticles (AuNP) using a scalable emulsion templating technique, resulting in nano-sized capsules that can sense changes in mechanical stress.
- When embedded in an elastomer matrix, these nano-capsules exhibit reversible deformation and a shift in their optical properties when subjected to tension, allowing for effective strain detection.
