“…As shown in PEDOT:C (curve 1) and PEDOT:P2C1 (curve 2) spectra in the Fig. S3, the bands at bands at 1733 and 1678 cm -1 were assigned to C=O stretching of the COOH group [2][3][4] , suggesting the successful doping of ternary citrate into the PEDOT films. The bands at 1613 cm -1 for PEDOT:C and PEDOT:P2C1 spectra are considered to be the characteristic peak of the PEDOT-doped state, while the band at PEDOT:P spectrum shifted to around 1602 cm -1 .…”

Neuroprosthetics, with a range of applications such as cognitive, auditory, pain relief, recording, motor, and visual prosthetics have emerged as a promising field in recent years. However, poor electrical conductivity, a high disparity between tissue and interfaces and the onset of reactive gliosis post-implantation remains major challenges in the development of neuroprostheses. The choice of biomaterials in designing the neural interfaces’ in neuroprosthetic applications is of high importance, as the overall sustained performance of neuroprosthetic devices is based on the features of materials used for the neural interfaces. Numerous biomaterials, such as metals and carbon-based materials, have been used in neuroprosthetics thus far. Nonetheless, neuroprosthetics made from polymeric biomaterials are in high demand due to their high biocompatibility, conductivity, and biostability. Furthermore, polymeric biomaterials can be used as a hybrid design to overcome the limitations of other co-biomaterials. This article makes an attempt to review the polymeric biomaterials involved in this cutting-edge technology utilized for different purposes such as substrates, coatings, and miniaturization of electrodes, that might help in enriching our understanding on neuroprosthetics.

“…Conjugation along with the highly hydrophobic surface of CNT and GN allows them to interact with the ICPs via hydrophobic and electrostatic interactions. Hence, a synthetic customized approach for developing a novel type of biosensor using this combination will give an entirely different carbon‐based ICP composite with a new set of fascinating properties . Selectivity of a biosensor largely depends upon the recognition element (e.g., antibody) and also on the type of host matrix and the interaction between them.…”

Biosensors are analytical devices which find extensive applications in fields such as the food industry, defense sector, environmental monitoring, and in clinical diagnosis. Similarly, intrinsically conducting polymers (ICPs) and their composites have lured immense interest in bio‐sensing due to their various attributes like compatibility with biological molecules, efficient electron transfer upon biochemical reactions, loading of bio‐reagent, and immobilization of biomolecules. Further, they are proficient in sensing diverse biological species and compounds like glucose (detection limit ≈0.18 nm), DNA (≈10 pm), cholesterol (≈1 µm), aptamer (≈0.8 pm), and also cancer cells (≈5 pm mL−1) making them a potential candidate for biological sensing functions. ICPs and their composites have been extensively exploited by researchers in the field of biosensors owing to these peculiarities; however, no consolidated literature on the usage of conducting polymer composites for biosensing functions is available. This review extensively elucidates on ICP composites and doped conjugated polymers for biosensing functions of copious biological species. In addition, a brief overview is provided on various forms of biosensors, their sensing mechanisms, and various methods of immobilizing biological species along with the life cycle assessment of biosensors for various biosensing applications, and their cost analysis.
