Abstract

An electrochemical platform composed of a biocompatible cerasome and cholesterol oxidase for cholesterol sensing.

Construction of a quaternary ammonium salt platform with different alkyl groups for antibacterial and biosensor applications

“…The prepared dispersion (5 mL) was deposited onto the surface of a pretreated GCE. According to Song's work, 5 chitosan sol (8 mL, 1 wt%) was added to encapsulate the GCE. The dried uniform lm-modied GCE was stored at 4 C. Here, the driving force of adsorption between Hb and DM-modied GCE were electrostatic and van der Waals interactions.…”

“…[1][2][3] Several synthetic materials have been used to immobilize proteins for constructing electrochemical biosensors, including insoluble surfactants, hydrogel polymers, and biopolymers. 4,5 Antibacterial agents have drawn increasing attention because of their high antibacterial efficacy and chemical stability. [6][7][8][9] In general, the most common antimicrobial reagents (oxidants and electrophilic agents 10,11 ) are highly toxic and harmful to the environment.…”

A Novel Amperometric Glucose Biosensor Based on Fe3O4‐Chitosan‐β‐Cyclodextrin/MWCNTs Nanobiocomposite

“…It can be seen in Figure S1b that the redox peak currents increase in good linearity with the increasing scan rate, indicating that that a surface‐controlled process of redox reaction of GOx at the surface of electrode. Furthermore, the average surface concentration ( Γ ) of GOx immobilized on the Fe 3 O 4 −CS−CD/MWCNTs/GOx/GCE was determined according to Faraday's law[35] …”

Nano‐spaced Gold on Glassy Carbon Substrate for Controlling Cell Behavior

“…Being inert also entails limitations as chemical and biological sensing typically require physical or chemical attachments of reactive species on the GC surface. For this reason, several GC works involve surface functionalization schemes for biosensing by decorating the material´s surface by solvothermal deposition [ 30–35 ] and by electrodeposition in solution. [ 35,36 ] In particular, noble‐metal nanoparticles (NPs), either by doping of or surface attachment to carbon films, have been extensively studied [ 35,37–41 ] because of their versatility, chemical stability, [ 42,43 ] and unique optical properties.…”
