1) Silk Fibroin as an Immobilization Matrix for Sensing Applications-ACS BIOMATERIALS SCIENCE AND ENGINEERING

DOI:10.1021/acsbiomaterials.1c00080

ABSTRACT:

The development of flexible, biocompatible, and environment-friendly sensors has attracted a significant amount of scientific interest for the past few decades. Among all the natural materials, silk fibroin (SF), due to its tunable biodegradability, biocompatibility, ease of processing, presence of functional groups, and controllable dimensions, has opened up opportunities for immobilizing multitudinous biomolecules and conformability to the skin, among other attractive opportunities. The silk fibroins also offer good physical properties, such as superior toughness and tensile strength. The sensors made of SF as an immobilization matrix have demonstrated excellent analytical performance, sensing even at low concentrations. The significant advantage of silk fibroins is the presence of functional groups along with a controllable conformation transition that enables immobilization of receptor molecules using silk fibroins as an immobilization matrix enables us to entrap the receptor molecules without using any chemical reagents. This review encompasses a detailed discussion on sensors, the advantages of using silk fibroins as an immobilization matrix for various receptors, their applications, and the future research scope in this state-of-the-art technology based upon the explorable applications for silk fibroin-based sensors.

ABSTRACT:

The two-dimensional (2D) materials are often mentioned as the wonder materials that will lead this era of science. They are vouched as the perfect solution to many of the world's problems. The 2D carbides, nitrides, and carbonitrides of transition metals, known by the name MXenes, contributes one amongst the largest 2D material family. MXenes efficaciously combine with polymers, ceramics, metals, and nanoparticles to form composites elucidated enhanced performance. Their unique chemical and physical properties render them excellent optical, electronic, structural, mechanical, and thermal properties. They have already found their place in several applications such as energy storage (910 mA h g−1 capacity at 100 mA g−1), sensors, electromagnetic interference (EMI) shielding (SE ≈ 57 dB at 0.009 mm thickness), catalysis, biomedical (imaging, drug delivery, GBR), tribology (98.4% reduction in COF), environmental, and so on. Their scalable production technique opens them up to a great variety of industrial applications. This article discusses the structure, synthesis, properties, and several industrially important applications of MXene and MXene based composites.
