Abstract

A novel nanorod-like MoS2 semiconductor nanostructure was synthesized through a simple two-step method. Nanorod-like MoS2 nanostructure was exploited as electrode material to immobilized enzyme and electrochemical sensing application. Characterizations of...

Freezing-assisted reverse microemulsion synthesis of hollow mesoporous silica encapsulated glucose oxidase

“…Many nanomaterials, such as metal oxide nanoparticles and metal sulfide nanoparticles, have been successfully used for the immobilization of GOx to prepare third generation of enzyme biosensors based on direct electron transfer. [30][31][32][33][34] However, the serious leakage of enzymes can occur when GOx-containing nanomaterials were exposed to the reaction solution. Therefore, it is still a great challenge to maintain the bioactivity of GOx through the sol-gel immobilization method.…”

A flexible electrochemical glucose sensing platform based on an electrospun PVA mat covered with in situ grown silver nanoparticles and a mixed self-assembled monolayer of glucose oxidase and ferrocene

“…19,20 Therefore, in many cases, introducing specific redox mediators into enzyme-based detection systems is an effective and necessary strategy that could facilitate electron transfer between enzymes and electrodes and make it possible to avoid oxygen reduction potential during detection. 21,22 Among the various redox mediators, ferrocene (Fc) and its derivatives are some of the most commonly used ones due to their favorable electrochemical properties and easy availability from commercial sources. By incorporating these redox mediators into enzyme-based detection systems, the transduction of glucose sensing shifts from oxygen monitoring to monitoring the electrochemical signals of Fc.…”

Molybdenum disulfide (MoS2)-based nanostructures for tissue engineering applications: prospects and challenges

“…molybdenum, and sulfur also play a key role in maintaining biological systems. 27 All these characteristics along with the key attribute of MoS 2 of having very high specific surface area makes imperative utilization of this fascinating material across diverse biomedical applications, which include but are not limited to drug delivery, 28,29 antibacterial activity, [30][31][32] biosensing, 33,34 and theranostics. 35,36 Humans have always envisaged the revamping of damaged organs and tissues with passable functioning, an aspiration, which is feasible using tissue engineering.…”
