Drug design and development are crucial areas of study for chemists and pharmaceutical companies. Nevertheless, the significant expenses, lengthy process, inaccurate delivery, and limited effectiveness present obstacles and barriers that affect the development and exploration of new drugs. Moreover, big and complex datasets from clinical trials, genomics, proteomics, and microarray data also disrupt the drug discovery approach.

This review article provides an inclusive overview of the intricate interactions amid ionic liquids (ILs) and essential biomacromolecules, mainly hemoglobin (Hb), bovine serum albumin (BSA), human serum albumin (HSA), and calf thymus-DNA (CT-DNA). ILs have recently become a topic of great attention because of their inimitable physicochemical properties and potential uses in different fields. The review systematically explores the binding mechanisms, thermodynamics, and structural changes induced by ILs on Hb, BSA, HSA, and CT-DNA using spectroscopic, thermodynamic, and computational techniques.

Article Synopsis
  • Multicomponent self-assembly in peptide nanotechnology allows for the creation of advanced nanomaterials with improved physical and biological properties by mimicking the natural extracellular matrix.
  • The combination of bioactive peptides and polymers is gaining popularity for developing novel biomaterials due to their customizable properties, biocompatibility, and biodegradability, particularly enhancing the mechanical strength of peptide hydrogels.
  • Research on composite scaffolds made from cellulose nano-fiber and cationic Cardin-motif peptide shows that the right mixing ratio enhances cellular responses and survival, making it a strong candidate for tissue engineering applications.

The goal of this research is to develop and characterize low-cost NHI doped polyvinyl alcohol (PVA)-4-ethyl-4-methylmorpholiniumbromide (ionic liquid) anion exchange membranes (AEM) and its application for membrane cathode assembly. Physical characterization like FTIR, POM, and XRD notified the functional groups, basic structure, and amorphosity of the produced membrane, and it was employed in single-chambered microbial fuel cells (sMFCs) as a separator. The membranes in terms of oxygen diffusion, proton conductivity, and ion exchange capabilities were evaluated.

The translocation of proteins from the cytoplasm to the endoplasmic reticulum occurs via a conserved Sec61 protein channel. Previously, we reported that mutations in histones cause downregulation of a CUP1 copper metallothionein, and copper exposure inhibits the activity of Sec61. However, the role of epigenetic dysregulation on the activity of channel is not clear.
