Gel-Based Luminescent Conductive Materials and Their Applications in Biosensors and Bioelectronics

Abstract

The gel is an ideal platform for fabricating materials for bio-related applications due to its good biocompatibility, adjustable mechanical strength, and flexible and diversified functionalization. In recent decades, gel-based luminescent conductive materials that possess additional luminescence and conductivity simultaneously advanced applications in biosensors and bioelectronics. Herein, a comprehensive overview of gel-based luminescent conductive materials is summarized in this review. Gel-based luminescent conductive materials are firstly outlined, highlighting their fabrication methods, network structures, and functions. Then, their applications in biosensors and bioelectronics fields are illustrated. Finally, challenges and future perspectives of this emerging field are discussed with the hope of inspire additional ideas.

Bigel Formulations of Nanoencapsulated St. John’s Wort Extract—An Approach for Enhanced Wound Healing

“…Gels are among the most often exploited semisolid dosage forms for dermal application. They structurally represent a three-dimensional network with liquid molecules entrapped between its units [14]. On the basis of the nature of the employed solvent, they are classified into two major groups: hydrogels, containing polar liquids (i.e., purified water [15]), and organogels, comprising nonpolar solvents, typically mineral or vegetable oils [16].…”

Nanomaterials-Functionalized Hydrogels for the Treatment of Cutaneous Wounds

“…Hydrogels are crosslinked 3D networks that swell with large amounts of water [26,27]. They have been widely used in dressings because they can keep the wound moist, cool the wound, absorb inflammatory exudates from the wound, provide a breathable microenvironment, prevent anaerobic bacteria from colonizing, and release preloaded therapeutic agents [28][29][30][31].…”
