We have developed a photostable nanocrystal-silica (NC-silica) laser that is robust under different chemical environments, making it suitable for integration with a microfluidic network. We demonstrate that the optical properties of this microscale laser can be a dynamic function of its local environment, thus providing a platform for potential applications such as nonlinear optical chemosensing on a miniaturized scale.
