“…In the BSA and PdNNs interaction, the negative value of ∆S° (-274.832 Jmol − 1 K − 1 ) indicates hydrophilic interaction. A negative value of ∆H° (-109.295 KJmol − 1 ) indicated the hydrogen bonding between BSA and PdNNs [54].…”

Bioinorganic chemistry has achieved great importance by considering environmental and health issues. Here we present anticancer, antioxidant, good protein quencher single pot biosynthesized one dimensional palladium Nanoneedles (PdNNs) as a negative catalyst, where water plays a role of safer solvent. Needle-shaped one-dimensional PdNNs was synthesized using filamentous fungal stain of Aspergillus oryzae (biomass) was successively applied as a suppressant for the growth of human breast, colon and leukemia cancer Cell Lines. Quenching process of bovine serum albumin by PdNNs was spontaneous with hydrogen bonding and hydrophilic interaction. Interaction of protein and PdNNs showed binding constant in the range of 104 M-1 and one binding site. Forster's resonance energy transfer (FRET) theory applied to find out distance between the interaction of PdNNs and protein, where critical distance and energy transfer distance varies with change in concentrations of PdNNs 4.84 x 10−6 M to 9.69 x 10-7 M from 2.9 to 3.7 nm and 3.2 to 5.4 nm respectively. Radical scavenging method was applied to find out an antioxidant activity which of nanoneedles. Needle-shaped palladium nanoparticles and particle size found to be ̴ 3.0 nm using high-resolution transmission electron microscopes.

“…topics have been central in previous reports (see references [104][105][106][107][108][109][110][111][112][113][114][115][116], (Figure 61), [117,118], (Figure 62), [119] (Figure 63), [120][121][122][123][124][125][126][127][128][129] Karimi et al synthesized carbon nanotube-cadmium selenide nanocomposites by electrophoretic deposition. From their investigation with the variation of 30%, 40%, 50%, 80%, and 90% also 120 V, 160 V, 200 V and 240 V potential, it is known that the optimum conditions for the synthesis of these materials is 50% of carbon nanotube; the yield of quantum dot deposition is 0.00035 g•cm −2 using 240 V. These results are also in line with the luminescence data in which it is found that 50% of carbon nanotube-cadmium selenide composite has the highest intensity of the others studied.…”

In this review from literature appearing over about the past 5 years, we focus on selected selenide reports and related chemistry; we aimed for a digestible, relevant, review intended to be usefully interconnected within the realm of fluorescence and selenium chemistry. Tellurium is mentioned where relevant. Topics include selenium in physics and surfaces, nanoscience, sensing and fluorescence, quantum dots and nanoparticles, Au and oxide nanoparticles quantum dot based, coatings and catalyst poisons, thin film, and aspects of solar energy conversion. Chemosensing is covered, whether small molecule or nanoparticle based, relating to metal ion analytes, H2S, as well as analyte sulfane (biothiols—including glutathione). We cover recent reports of probing and fluorescence when they deal with redox biology aspects. Selenium in therapeutics, medicinal chemistry and skeleton cores is covered. Selenium serves as a constituent for some small molecule sensors and probes. Typically, the selenium is part of the reactive, or active site of the probe; in other cases, it is featured as the analyte, either as a reduced or oxidized form of selenium. Free radicals and ROS are also mentioned; aggregation strategies are treated in some places. Also, the relationship between reduced selenium and oxidized selenium is developed.

Chitosan biological macromolecule is a versatile polymer; chemical modification has been carried out that lead to the formation of chitosan grafted polymers composites (Chito-g-PC). We proposed synthesis of six various Chito-g-PC as sorbents for toxic dyes. A novel graft copolymerization method based on radical polymerization with vinyl monomer like acrylic acid, acrylamide, N-isopropylacrylamide, methacrylic acid and polyacrylonitrile were utilized in order to address the large amount of swelling at four different pH buffers solution. The effect of initiator and monomer concentration, time and temperature on % grafting and % grafting efficiency were performed. Comparative characterization of Chito and Chito-g-PC were evaluated by SEM, XRD and FTIR, as well as solubility characteristics of the composites were determined by various pH buffer solution. Cationic toxic dyes Malachite green (MG) and Methylene blue (MB) were selected as the sorbet, and Chito-g-PC were used as biosorbents. Thermodynamic analysis showed that the sorption process was spontaneous and endothermic with an increased randomness. The sorption experiments were realized with six different Chito-g-PC for MG and MB at various pH.
