“…16,75 In this regard, fibroin has been extensively studied and stands out against other materials thanks to its unique properties, which include being mechanically robust 1,14,74 and transparent throughout the visible spectrum, presenting smooth surface and variable refractive index, [81][82][83] and being susceptible to physical changes in its structure. 76,77 All these characteristics allow the preparation of passive or active devices 75 based on pure fibroin 16 or fibroin in the presence of other components, 167 to provide materials like supports for electrodes, 16,221 lasers, [168][169][170][171][172][173][174] biosensors, [175][176][177][178][179][180] waveguide, 83,181,182 fuel cells, 183 and energy storage devices. 184 Kim and collaborators built an electrode consisting of a chip supported on an ultrathin and resorbable fibroin substrate.…”

The silk produced in the Bombyx mori’ glands and used in the preparation of the cocoons has been employed in the textile industry millennia ago in fabric production. These cocoons are composed mainly of fibroin (SF, Silk Fibroin), a fibrous protein that presents unique mechanical properties, in addition to being a biocompatible, biodegradable and low-cost source. This protein can be extracted from these cocoons by being processed in aqueous medium and used to obtain the most diverse materials for different applications, such as biomaterials development as body implants and in the composition of the scaffolds for tissue engineering, moreover to photonic devices as sensors, waveguides and lasers.

“…Recently, different gain-medium-infiltrated biological materials, such as disordered protein crystals, marine, skeleton, human colon tissues, and interestingly, living cell suspensions, have been shown to support random lasing action. − In particular, the spectral characteristics of random lasing are strongly dependent on the scattering properties of the biological host material, − providing a promising tool for the characterization of biophysical properties. However, applying random lasing to biopsies is still challenging, considering the poor biocompatibility of laser dyes and the limited understanding of the intercellular and intracellular biophysical properties. − …”

A random laser carrying the scattering information on a biological host is a promising tool for the characterization of biophysical properties. In this work, random lasing from label-free living cells is proposed to achieve rapid cytometry of apoptosis. Random lasing is achieved by adding biocompatible gain medium to a confocal dish containing cells under optically pumped conditions. The random lasing characteristics are distinct at different stages of cell apoptosis after drug treatment. By analyzing the power Fourier transform results of the random lasing spectra, the percentage of apoptotic cells could be distinguished within two seconds, which is more than an order of magnitude faster than traditional flow cytometry. These results provide a label-free approach for rapid cytometry of apoptosis, which is advantageous for further research of random lasers in the biological field.

“…Mechanisms and structures of random lasers have been extensively studied, including Anderson light localization to glassy-light behavior and the interplay between homogeneously dispersed plasmonic nanoparticles [ 9 , 10 , 11 , 12 ]. Graphene is a single layer, or just a few layers, of graphite that has outstanding electronic, mechanical, and optical characteristics, as well as thermal and chemical stability [ 13 , 14 ].…”

An improvement in random lasers based on a colloidal quantum dot (QD)/graphene-doped polymer was observed and attributed to multiple light-scattering and graphene surface plasmon resonance. The emission characteristics of quantum dots doped with graphene oxide and reduced graphene oxide were compared. The QD/reduced graphene oxide hybrid exhibited a lower laser emission threshold (~460 μJ/cm2). The emission modes and thresholds were strongly dependent on both the graphene doping concentration and the external temperature. Decreased plasmon coupling was the primary reason for lower QD/graphene laser emission with increasing temperature. The optimum reduced graphene oxide concentration was 0.2 wt.%. This work provides a practical approach to optimizing the threshold and stability of random laser devices, with potential applications in displays, sensors, and anti-counterfeiting labels.
