Abstract
The binding interaction of cannabidiol (CBD) and human serum albumin (HSA) under physiological blood pH conditions (pH 7.4) was conducted by surface plasmon resonance (SPR), fluorescence spectroscopy, UV-Visible spectrophotometry, and molecular docking. The responses from SPR measurement increased with the increase in CBD concentration until equilibrium was reached at the equilibrium dissociation constant (KD) of 9.8 × 10-4 M. The results from fluorescence and UV-Visible spectroscopy showed that CBD bound to HSA at one site in a spontaneous manner to form protein-CBD complexes. The quenching process involved both static and dynamic mechanisms while the static mechanism contributed predominantly to the binding between CBD and albumin. The binding constants estimated from the fluorescence studies were from 0.16 × 103 to 8.10 × 103 M-1, which were calculated at different temperature conditions using Stern-Volmer plots. The thermodynamic parameters demonstrated that the binding interaction was a spontaneous reaction as Gibbs free energy had negative values (ΔG = -12.57 to -23.20 kJ.mol-1). Positive ΔH and ΔS values (ΔH = 2.46 × 105 J.mol-1 and ΔS = 869.81 J.mol-1K-1) indicated that the hydrophobic force was the major binding interaction. Finally, confirmation of the type and extent of interaction was provided using UV-spectroscopy and molecular docking studies. The outcomes of this study are expected to serve as a platform to conduct future studies on binding interactions and toxicological research of CBD.Communicated by Ramaswamy H. Sarma.

Abstract
Extensive research has been carried out to investigate the stability and function of human serum albumin (HSA) when exposed to surface-active ionic liquids (SAILs) with different head groups (imidazolium, morpholinium, and pyridinium) and alkyl chain lengths (ranging from decyl to tetradecyl). Analysis of the protein fluorescence spectra indicates noticeable changes in the secondary structure of HSA with varying concentrations of all SAILs tested. Helicity calculations based on the Fourier transform infrared (FTIR) data show that HSA becomes more organized at the micellar concentration of SAILs, leading to an increased protein activity at this level. Small-angle neutron scattering (SANS) data confirm the formation of a bead-necklace structure between the SAILs and HSA. Atomistic molecular dynamics (MD) simulation results identify several hotspots on the protein surface for interaction with SAIL, which results in the modulation of protein conformational fluctuation and stability. Furthermore, fluorescence resonance energy transfer (FRET) experiments with the intramolecular charge transfer (ICT) probe trans-ethyl p-(dimethylamino) cinnamate (EDAC) demonstrate that higher alkyl chain lengths and SAIL concentrations result in a significantly increased energy transfer efficiency. The findings of this study provide a detailed molecular-level understanding of how the protein structure and function are affected by the presence of SAILs, with potential implications for a wide range of applications involving protein-SAIL composite systems.

Abstract
The biological relevance of G4 structures formed in telomere & oncogenes promoters make them extremely crucial therapeutic target for cancer treatment. Herein, we have synthesized chitosan-based gold nanoparticles (CH-Au NPs) through green method and have investigated their interaction with G4 structures formed by short telomeric sequences to evaluate their potential for targeting G4 structures. Firstly, we have characterized morphological/physical attributes of synthesized CH-Au NPs and salt dependent structural aspects of model G-rich DNA sequence, 12-mer d(T2G4)2 [TETRA] using spectroscopic and biophysical techniques. The molecular interactions between CH-Au NPs and parallel/antiparallel TETRA G4 structures were evaluated using UV-Visible, CD, Fluorescence, CD melting, DLS and Zeta potential studies. The experimental data indicated that CH-Au NPs showed strong binding interactions with Parallel TETRA G4 and provided thermal stabilization to the structure, whereas their interactions with Antiparallel TETRA G4 DNA and Ct-DNA (DNA duplex) were found to be negligible. Further, CH-Au NPs were also investigated for their selectivity aptitude for different G4 structures formed by human telomeric sequences; d(T2AG3)3 [HUM-12] and d(T2AG3)4T [HUM-25]. Our findings suggested that CH-Au NPs exhibited topology specific binding aptitude towards G4 structure, which can be utilized to inhibit/modulate crucial biological functions for potential anticancer activity.

Abstract
Ionic liquids (ILs) can stabilize or destabilize proteins, which motivates us to examine their effect on hemoglobin. The native state of hemoglobin (Hb) is disrupted at different physical conditions such as pressure, temperature, and solvents. Herein, we have monitored the stability of Hb in a nontoxic and biocompatible IL, i. e., choline amino acid-based Ils (ChAAILs), using various spectroscopic techniques like UV-Vis and fluorescence spectroscopy, circular dichroism (CD), and isothermal titration calorimetry (ITC) measurements. It was observed that Hb stays neither in its native state nor in its fully denatured state; rather, it achieves an intermediate state in the presence of ChAAILs. The research on the intermediate state of Hb is still unexplored. Research has been pursued to find a suitable ligand or IL that can stabilize the intermediate state of Hb. In that context, ChAAILs are among the best choices. Molecular docking studies unravel the binding of ChAAILs with Hb. The obtained binding energies of the docked complex are -7.2 kcal/mol and -8.7 kcal/mol for binding of Hb with [Chl][Gly] and [Chl][Met], respectively, which was in line with the ITC results. The quantum chemical calculations show that H-bond plays a significant role for the interaction between Hb and ChAAILs.

Abstract
A facile synthesis of glutathione-stabilized copper nanoclusters (CuNCs) is carried out in H2O/ tetrahydrofuran medium. The photophysical and morphological studies performed with as-synthesized CuNCs revealed the formation of green-emissive, stable, and smaller nanoclusters. The precise composition of these as-synthesized CuNCs was predicted with the aid of electrospray ionization mass spectrometry analysis as Cu12(SG)9. Furthermore, the systematic studies of the interaction of synthesized CuNCs with three plasmatic proteins, namely, bovine serum albumin (BSA), lysozyme (Lys), and hemoglobin (Hb) have been performed by using a series of spectroscopic studies. The conformational changes in these proteins upon interacting with CuNCs and their binding stoichiometries have been investigated from the combination of UV-visible and steady-state fluorescence measurements. The changes in the microenvironment of proteins caused by CuNCs were investigated by circular dichroism spectroscopy. Among these three proteins, BSA and Lys had a minor effect on the luminescence of CuNCs, which makes them suitable candidates for biological applications. There are no drastic changes in the microenvironment of NCs as well as proteins because of the possibilities of weak electrostatic and H-bonding interactions of CuNCs with BSA and Lys. The feasibility of strong metallophic interaction between the Fe2+ present in the heme group of Hb and Cu(I) or -S atoms present in the CuNCs brings considerable changes in the photophysical activity of CuNCs and their interactions with Hb. The functional groups on NCs as well as active amino acid residues present in proteins play a crucial role in determining their interactions. This work shed a piece of knowledge on designing NCs for specific biological applications.

Abstract
The present study was designed to explore the hydrophobicity and concentration dependence of imidazolium based surface active ionic liquids (SAILs) effects on the structural-functional integrity of proteins. Specifically, we investigated the impact of SAILs viz. 1-octyl-3-methylimidazolium dodecylbenzenesulfonate ([OMIM][DBS]) and 1-dodecyl-3-methylimidazolium dodecylbenzenesulfonate ([DDMIM][DBS]) on activity, structure and stability of lysozyme. Activity measurements revealed that, in contrast to [DDMIM][DBS] that renders lysozyme either feebly active or inactive, [OMIM][DBS] significantly enhances the lysozyme activity in the concentration range of critical aggregation concentrations (CAC) to Cs (SAIL saturation concentration of protein backbone) i.e., 0.5 mM-1.35 mM. Tensiometric results in agreement with turbidity measurements inferred significant composition and concentration dependence of the lysozyme-SAIL interactions. Spectroscopic investigations revealed that compared to destabilizing behaviour of [DDMIM][DBS], [OMIM][DBS] significantly enhances both conformational as well as thermal stability of lysozyme in the CAC to Cs concentration regime. Altogether, results obtained do indicate that [OMIM][DBS], in the concentration regime of CAC to Cs, serves as an efficient stabiliser with an ability to appreciably enhance the activity, thermal stability and overall conformational stability of lysozyme. We firmly believe that [OMIM][DBS], at least in the CAC to Cs concentration ranges, can be exploited as a promising stabiliser and activity enhancer for numerous industrially important enzymes.

Abstract
Iron detection is one of the critical markers to diagnose multiple blood-related disorders that correspond to various biological dysfunctions. The currently available anemia detection approach can be used only for pre-treated blood samples that interfere with the actual iron level in blood. Real-time detection approaches with higher sensitivity and specificity are certainly needed to cope with the commercial level clinical analyses. Herein, we presented a novel strategy to determine the blood iron that can be easily practiced at commercial levels. The blend of well-known iron-cyanide chemistry with nanotechnology is advantageous with ultrahigh sensitivity in whole blood analysis without any pre-treatments. This approach is a combined detection system of the conventional assay (UV-visible spectroscopy) with surface-enhanced Raman scattering (SERS). Organic cyanide modified silver nanoparticles (cAgNPs) can selectively respond to Fe3+ ions and Hb protein with a detection limit of 10 fM and 0.46 μg mL-1, respectively, without being affected by matrix interfering species in the complex biological fluid. We confirmed the clinical potential of our new cAgNPs by assessing iron-status in multiple anemia patients and normal controls. Our SERS-based iron quantitation approach is highly affordable for bulk-samples, cheap, quick, flexible, and useful for real-time clinical assays. Such a method for metal-chelation has extendable features of therapeutics molecular tracking within more complex living systems at cellular levels.
