Abstract: Provided are a porous silicone resin and a light-weight flexible flame-retardant composite material, belonging to the technical field of nano-porous materials. The porous silicon resin is prepared from a porous silicon resin precursor solution by means of curing and drying processes. The porous silicone resin precursor solution includes a flame retardant, a surfactant, a siloxane monomer, a catalyst, an auxiliary agent and a solvent. The porous silicone resin precursor solution is obtained by firstly dissolving the flame retardant and the surfactant in the solvent, and then adding the siloxane monomer, the catalyst and the auxiliary agent and mixing them uniformly. The porous silicone resin and the light-weight flexible flame-retardant composite material prepared therefrom have the excellent properties of high porosity, high flame retardancy, high elasticity and high strain.

Abstract: The present invention discloses a silicone rubber and a method for preparing it, and a phenolic modified silicone rubber resin and a method for preparing it. The structural formula of the silicone rubber is shown as follows: Wherein x=70-80, y=10-20.

Abstract: Disclosed are field effect transistor-based (FET-based) sensors for the rapid and accurate detection of analytes both in vivo and in vitro. The FET-based sensors can include a substrate, a channel disposed on the substrate, a source electrode and a drain electrode electrically connected to the channel, and a recognition element for an analyte of interest immobilized on the surface of the channel via a linking group. The distance between the recognition element and the channel can be configured such that association of the analyte of interest with the recognition element induces a change in the electrical properties of the channel. In this way, an analyte of interest can be detected by measuring a change in an electrical property of the channel. Also provided are devices, including probes and multi-well plates, incorporating the FET-based sensors.
