“…PTH, CMCS, and CS were blended with the cross‐linking agent glutaraldehyde (GA) to create a hydrogel with electroactive behavior. The synthesized hydrogel response was found to be inversely proportional to the strength of the applied DC electric field . The bending angle toward the electrode increased with increasing the electric field strength where the crosslinked CS/CMCS hydrogel has shown better performance than non‐crosslinked hydrogel.…”

Semiconducting polythiophenes display electroactive properties which make them excellent candidates for applications as electroactive materials. Ability to undergo doping and to switch between different oxidation states allow tuning the chemical and physical properties of polythiophenes. Furthermore, the ability to integrate polythiophenes into copolymers, hybrid composites with metals and inorganic materials make them useful in electronic and biomedical applications. The capability to vary the properties of the final material with low production cost and high processability into thin films makes polythiophenes desirable materials for many applications. © 2017 Wiley Periodicals, Inc.

“…Injectable hydrogels as drug delivery and implant materials have attracted increasing attention in the past decades due to their unique advantage of nonsurgical treatment to the patients . Environment sensitive hydrogels, also called “intelligent” or “smart” hydrogels can undergo reversible volume phase transitions or gel–sol phase transitions in response to the external stimuli such as pH, temperature, and glucose concentration, have been used extensively in diverse applications, such as in making artificial muscles, chemicalvalves, immobilization of enzymes and cells, and concentrating dilute solutions in bioseparation, especially in the development of smart drug delivery systems . Design of injectable gels using responsive polymers is, thus, becoming an interesting task because the resultant hydrogels can combine the performances of injectability and controlled release of drugs.…”

Injectable hydrogels with pH and glucose triggered drug release capability were synthesized based on biocompatible phenylboronic modified chitosan and oxidized dextran through the formation of covalent imine bond and phenylboronate ester. Rheological characterization demonstrated that the gelation rate was rapid, and the moduli of the hydrogels were able to be tuned with chemical composition as well as pH and glucose concentration of the polymer solution. Anticancer drugs could be incorporated inside the hydrogel through the in situ gel forming process and undergo a controlled release by altering pH or glucose concentration. The hydrogels had good biocompatibility with viable and proliferated cells cultured in the three dimensional matrix, and the cell proliferation was suppressed when a small amount of DOX was added, which is benefit for the application of the hydrogels as smart anticancer drug delivery system. © 2015 Wiley Periodicals, Inc.

“…Polyaniline (PANI), polypyrrole (PPy) and polythiophenes (Pth) as conjugated polymer backbones can be used for the fabrication of conducting polymer actuators [49]. Since PANI actuators are operated in acidic environment with pH < 4 [50] and Pth actuators reach comparably low strains (% deformation) in ionic liquid electrolytes [51], PPy actuators are most widely used in biomedical applications [52]. Generally, the dimensional changes in soft actuators made from conducting polymers are the result of ion and solvent influx (Figure 4a, mechanostimulation due to swelling).…”

Abstract:Organic bioelectronics forms the basis of conductive polymer tools with great potential for application in biomedical science and medicine. It is a rapidly growing field of both academic and industrial interest since conductive polymers bridge the gap between electronics and biology by being electronically and ionically conductive. This feature can be employed in numerous ways by choosing the right polyelectrolyte system and tuning its properties towards the intended application. This review highlights how active organic bioelectronic surfaces can be used to control cell attachment and release as well as to trigger cell signaling by means of electrical, chemical or mechanical actuation. Furthermore, we report on the unique properties of conductive polymers that make them outstanding materials for labeled or label-free biosensors. Techniques for electronically controlled ion transport in organic bioelectronic devices are introduced, and examples are provided to illustrate their use in self-regulated medical devices. Organic bioelectronics have great potential to become a primary platform in future bioelectronics. We therefore introduce current applications that will aid in the development of advanced in vitro systems for biomedical science and of automated systems for applications in neuroscience, cell biology and infection biology. Considering this broad spectrum of applications, organic bioelectronics could lead to timely detection of disease, and facilitate the use of remote and personalized medicine. As such, organic bioelectronics might contribute to efficient healthcare and reduced hospitalization times for patients. OPEN ACCESSElectronics 2015, 4 880
