Tissue engineering is an interdisciplinary field that aims toward the repair of the tissues and organs by bringing together the chemists, material scientists, and biologists to work in coordination for a better understanding of cell−polymer interactions. The leading challenge in the field of tissue engineering is to mimic the naturally occurring extracellular matrix due to which scaffold engineering has become the central area of research in this field. Various materials have been investigated for the fabrication of scaffolds; silk-based composites are among the most promising materials because of their secure processing, adequate mechanical strength, biodegradability, biocompatibility, hemocompatibility, and oxygen and water permeability. This review extensively focuses on the silk-based composite scaffolds, their fabrication, sterilization, and applications in tissue engineering.

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.

“…The use of electrospinning methods has received substantial curiosity, since the fibers have sought a myriad of applications in fields such as effluent treatment, , electroless plating, radioactive element reclamation, , chillers and heat exchangers, superhydrophobic composites, oil–water separation, , EMI shielding, , and biomedical applications. − As a result, the fabrication of phase-change fibers using electrospinning has now gained the attention of researchers, thanks to their unique characteristics as excellent thermal attributes, increased surface-to-volume ratio, and ultrafine size. Accordingly, Wenmin et al constructed a shape-stable PEG-cellulose acetate core–sheath smart fabric by coaxial electrospinning for temperature adaptation, where they depicted that the latent heat storage values varied by varying the weight percentage of PEG.…”

Phase-change materials (PCMs) are utilized for thermal energy storage (TES) to bridge the gap between supply and demand of energy. Organic PCMs, similar to paraffins, fatty acids, and polyethylene glycol, are extensively explored, thanks to their high TES capacity (∼5–10 times more than the sensible heat storage of water/rock), wide temperature range (spanning from −5 °C to 190 °C), good thermal stability over heating–cooling cycles (∼100 cycles), etc. However, “leakage” of PCMs upon transformation from solid to liquid has limited their usage as TES materials; thus, PCMs are confined to a biopolymeric framework for circumventing seepages. However, extensive analysis has concluded that there is a deficiency in availability of consolidated data on biopolymeric-based framework for PCMs. Thus, this review covers various literatures on the application of assorted biopolymers as framework for PCM. Simultaneously, we have also discussed on importance of biopolymers for constructing a framework for PCMs. Finally, the review concludes with future prospects, along with possibilities and disputes on the course of their practical application.
