“…Cationically charged antibacterial agent enters into the bacterial cell membranes, and this disturbs the integrity of membrane, ultimately killing the bacteria 28 (Figure 2). The conducting polymers such as polyaniline (PANI), 32 polypyrrole (PPy), poly(3,4‐ethylenedioxythiophene) (PEDOT), 33 and their composites 34–36 with metal or metal oxides such as Ag, 37,38 Au, 39 palladium (Pd), 40 copper oxide (CuO), 41 and ZnO 42 for imparting antibacterial properties are well reported in the literature 43–45 . For instance, a composite of PPy with dextrin exhibited antibacterial activity against the gram‐positive and gram‐negative bacteria 34 .…”

With the advancement of applications in biomedicines and bioelectronics, conducting polymers have attained huge significant attention. For such applications, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is considered a potential conducting polymer because of its low cost, considerable stability, high conductivity and mechanical strength. Most importantly, its easy aqueous solution processability makes it more attractive. Over the last few years, PEDOT: PSS has been predominantly explored and investigated for different optoelectronic flexible devices, and recently it has been studied for biomedical applications.PEDOT:PSS based materials have made progress in biomedicines due to their properties such as biocompatibility, cell proliferation, antibacterial, nontoxicity and so forth. To adjust the desirable properties, special attention is required for altering the structure of PEDOT:PSS material. PEDOT:PSS offers excellent antibacterial properties against both gram-positive and gram-negative bacteria. Moreover, PEDOT:PSS demonstrates an important role in sensing human body humidity, pressure control, glucose detection, as well as employed in human sweat sensors. Besides these, PEDOT:PSS has been studied as a scaffold for endothelial cell preservation. There are several issues which need to be resolved in the future, such as improved biocompatibility and stability to explore the PEDOT:PSS based composite materials in biomedical applications. However, a related review article is lacking, directed on the PEDOT:PSS biomedical applications, namely, antibacterial, tissue engineering, and biosensing. Therefore, the current article summarizes importance of PEDOT:PSS for biomedical applications, and main emphasis is given to its recent advances, challenges and perspectives.

“…AuNPs have been extensively studied for amplifications of the electrode signal and nanoenzyme properties in biosensors due to their simple synthesis and reproducibility [132]. AuNPs have been widely explored in many applications including chemical and biological sensing, solar cells, catalysis, biomedical, infrared radiation absorbing optics, photo thermal therapy and tissue/tumor imaging [133]. Polymeric nanocomposites with embedded AuNPs are used in biomedical and bioanalytical applications for the design of chemical biosensors [134].The incorporation of gold nanoparticles (AuNPs) into PANI matrix has been extensively studied because Au/PANI nanocomposites, through the combination of both components reveal characteristics such as good biocompatibility, large surface areas, good electrochemical stability and enhanced electrocatalytic activity [135].…”

Polyaniline (PANI) is one of the most extensively used conducting polymer due to its fascinating properties including conducting, thermal, optical, magnetic and electrochemical properties, simple synthesis procedure and low cost of monomer. It has attracted major attention in a variety of applications including electrochemical sensors, catalysts, supercapacitors and biosensors. However, its limitations such as insolubility in common solvents, low process‐ability and poor mechanical properties have led to the development of new approaches to improve it properties. Metal nanoparticles (MNPs) such as silver, gold, copper and palladium have been combined with PANI to improve on its properties which has led to a new class of materials known as metal/PANI nanocomposites. These hybrid nanocomposites incorporate advantages of both MNPs and polymers which effectively improves the properties of the individual materials. Various synthesis techniques including in situ polymerization, ɤ‐radiolysis, electrodeposition, complexation, vacuum deposition and interfacial polymerization have been used in the formation of metal/PANI nanocomposites. These nanocomposites have been used in various sensor and biosensor applications due to their excellent conductivity, ease of synthesis, excellent redox potentials, chemical and thermal stability. This review highlights the various metal/PANI nanocomposites, their various synthesis techniques and their application in sensors and biosensors. The importance of these nanocomposites in sensing and signaling various toxic heavy metals such as mercury, lead and silver and toxic gases such as hydrogen sulphide, ammonia and chloroform has been discussed. In addition the review covers the applications of metal/PANI nanocomposites in biosensor systems for the detection of glucose, DNA, protein, cholesterol, drugs and hydrogen peroxide.
