Abstract
Glutathione-capped copper sulfide (CuxSy) nanoparticles with two different average sizes were successfully achieved by using a simple reduction process that involves only changing the reaction temperature. Temperature-induced changes in the size of CuxSy nanoparticles resulted in particles with different optical, morphological, and electrochemical properties. The dependence of electrochemical sensing properties on the sizes of CuxSy nanoparticles was studied by using voltammetric and amperometric techniques. The spherical CuxSy nanoparticles with the average particle size of 25 ± 0.6 nm were found to be highly conductive as compared to CuxSy nanoparticles with the average particle size of 4.5 ± 0.2 nm. The spherical CuxSy nanoparticles exhibited a low bandgap energy (Eg) of 1.87 eV, resulting in superior electrochemical properties and improved electron transfer during glucose detection. The sensor showed a very good electrocatalytic activity toward glucose molecules in the presence of interference species such as uric acid (UA), ascorbic acid (AA), fructose, sodium chloride, and sucrose. These species are often present in low concentrations in the blood. The sensor demonstrated an excellent dynamic linear range between 0.2 to 16 mM, detection limit of 0.2 mM, and sensitivity of 0.013 mA/mM. The applicability of the developed sensor for real field determination of glucose was demonstrated by use of spiked blood samples, which confirmed that the developed sensor had great potential for real analysis of blood glucose levels.

Abstract
Background: It is widely acknowledged that pathogenic germs delay wound healing to some extent. To explore factors influencing the wound healing process, the current study was conducted to evaluate the antibacterial effect of topical application of copper sulfide nanoparticles (CuS NPs) in vitro and on infected wound healing process in the rat model. Materials and Methods: In this study, the morphology and size of CuS NPs were detected. Staphylococcus aureus and Escherichia coli were used so that the antibacterial ability of CuS NPs could be evaluated better. In addition, a 2-cm circular full-thickness wound infected with a solution of 107 colony forming units (CFU) Staphylococcus aureus was created on the back of each rat. The rats were divided into four groups including the control group, the 100 mcg/mL CuS NPs group, the 250 mcg/mL CuS NPs group, and the 500 mcg/mL CuS NPs group. Tissue bacterial count and histologic assessment were evaluated. Results: The results indicated that CuS NPs had antibacterial activity against Staphylococcus aureus and Escherichia coli. Moreover, they could decrease the incidence of bacterial colonization and promote wound healing through re-epithelialization and collagen deposition. Furthermore, CuS NPs could maintain Cu2+ continuous release and inhibit the viability of Staphylococcus aureus through lipid peroxidation. Conclusions: This study found that CuS NPs have fine antibacterial properties, and particularly, the 500 mcg/mL CuS NPs had better effects, without increase of side effects. They could promote infected wound healing, the prospective clinical application of which was further confirmed in the treatment of wound infection.

Abstract
We report on the synthesis of chitosan-alginate nanodisks (Cs-Al NDs) using a simple approach consisting of the ionotropic gelation method. Sodium tripolyphosphate (STPP) was used as crosslinking agent to promote the electrostatic interaction between amine groups the chitosan and hydroxyl and carboxyl groups of alginate. Scanning electron microscopy (SEM) images provided direct evidence of the morphology of the nanodisks where agglomeration was observed due to the electrostatic interaction between the functional groups. Furthermore, dynamic light scattering (DLS) showed that the hydrodynamic size of the Cs-Al NDs was 227 nm and 152 nm in pH 1.2 and pH 7.4, respectively, which is in agreement with the information observed in the SEM images. The chemical structure is presented mainly the amine and carboxyl groups due to the presence of chitosan and alginate in the nanodisks, respectively, which allow the electrostatic interaction through N-H linkages. According to the X-ray diffraction, we found that the Cs-Al NDs exhibited the typical structure of chitosan and alginate, which lead the formation of polyelectrolyte complexes. We also evaluated the encapsulation of amoxicillin in the nanodisk, obtaining a loading efficiency of 74.98%, as well as a maximum in vitro release amount of 63.2 and 52.3% at pH 1.2 and 7.4, respectively. Finally, the cytotoxicity effect of the Cs-Al nanodisks was performed in human prostatic epithelial PWR-1E and Caucasian prostate adenocarcinoma PC-3 cell lines, in which the cell viability was above 80% indicating low inhibition and determining the Cs-Al NDs as a promising technology for controlled delivery systems.

Abstract
Here, we develop a visible light-triggered platform to activate the biomimetic activity of CuS nanoparticles by incorporating a photoacid generator. Under visible-light illumination, the remarkable pH decrease, caused by the intramolecular photoreaction of the photoacid generator, activates the peroxidase-like activity of the CuS nanoparticles. This visible light-triggered pH switch meets the antibacterial demands of peroxidase mimics perfectly in bacteria-infected wounds. Importantly, the built-in torches of mobile phones are able to replace the visible-light source to activate the peroxidase-mimicking activity of CuS nanoparticles to combat bacteria, which greatly promotes the utility and adaptability of this antibacterial platform. An in situ pH decrease is achieved under visible-light illumination on a photoacid generator, and thus activates the peroxidase-like activity of CuS nanoparticles to treat bacteria-infected wounds.![]()
