TL;DR
This paper demonstrates biocompatible microsphere solid-state biolasers made from biomaterials, with simple fabrication, low lasing threshold, and high Q factor, suitable for biological applications.
Contribution
It introduces a novel, simple emulsion-based fabrication method for biolasers using biomaterials like bovine serum albumin, pectin, and cellulose.
Findings
Lasing threshold of 1 microJ/mm2
Q factor of 3000 measured
Biocompatible with no interference in cell growth
Abstract
Microsphere solid-state biolasers made of biomaterials-bovine serum albumin, pectin and cellulose are demonstrated. The fabrication is simple, based on emulsion, and with green processing. A lasing threshold of 1 microJ/mm2 and Q factor of 3000 are measured. The lasers are biocompatible, do not interfere with cell growth and division.
