Silk-based biocompatible random lasing
TL;DR: A biocompatible random laser made entirely of doped silk, functional in aqueous media, showing clear threshold behavior and spectral narrowing and capable of probing changes in a chemical environment, namely, pH, is demonstrated.

Gain-Based Mechanism for pH Sensing Based on Random Lasing
TL;DR: In this article, the authors exploit random lasing in disordered systems with optical gain, without a need for periodic geometry or a carefully aligned cavity, and demonstrate a sensing scheme based on modification of the gain by the environment's $p$H.
Microsphere Solid‐State Biolasers
TL;DR: In this article, a whispering gallery mode microlaser with thresholds of a few µJ mm-2 and quality factors of up to 3000 was reported, which is compatible with cell growth and resistant to the aqueous environment of cell culture media.

Soraya Caixeiro,Matilda Peruzzo,Matilda Peruzzo,Olimpia D. Onelli,Silvia Vignolini,Riccardo Sapienza +5 more
TL;DR: In this article, a light-matter-interaction was used to optimise light scattering using cellulose nanocrystals, achieving a transport mean free path as low as 3.5 um in the visible light range.
