Descrição geral

Octamethyltrisiloxane, commonly referred to as octamethylcyclotetrasiloxane, falls under the category of siloxanes. Its versatile applications include serving as a solvent, coupling agent, and surface tension modifier in various industries. Furthermore, it plays a significant role in the production of adhesives, sealants, and lubricants.

Aplicação

Octamethyltrisiloxane is used as a solvent for good dispersion of styrene and polydimethylsiloxane (PDMS), which are used in the fabrication of perovskite barium titanate inverse opal films.

This paper proposes a high-throughput, function-based screening approach of a metagenomic library for isolating novel microbial enzymes by droplet-based microfluidics. We used gel microdroplets (GMDs) dispersed in oil as picoliter-volume reaction vessels for lipolytic enzyme by encapsulating cells in individual
