Novel and Facile Colorimetric Detection of Reducing Sugars in Foods via In Situ Formed Gelatin-Capped Silver Nanoparticles. Polymers (Basel) 2023; 15:polym15051086. [PMID: 36904327 PMCID: PMC10007220 DOI: 10.3390/polym15051086] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 02/19/2023] [Accepted: 02/20/2023] [Indexed: 02/25/2023] Open
Abstract
The evolution of green technology for the simple and ecological formation of silver nanoparticles (AgNPs) inspired the present work for simple and efficient detection of reducing sugars (RS) in foods. The proposed method relies on gelatin as the capping and stabilizing agent and the analyte (RS) as the reducing agent. This work may attract significant attention, especially in the industry, for testing the sugar content using gelatin-capped silver nanoparticles as it not only detects the sugar in food, but also determines the content (%), which could be an alternative technique to the conventionally used DNS colorimetric method. For this purpose, a certain amount of maltose was mixed with a gelatin-silver nitrate. Different conditions that may affect the color changes at 434 nm owing to the in situ formed AgNPs, such as gelatin-silver nitrate ratio, PH, time, and temperature, have been investigated. The 1:3 mg/mg ratio of gelatin-silver nitrate dissolved in 10 mL distilled water was most effective in color formation. The development of AgNPs color increases within 8-10 min at PH 8.5 as the selected optimum value and at the optimum temperature of 90 °C for the evolution of the gelatin-silver reagent's redox reaction. The gelatin-silver reagent showed a fast response (less than 10 min) with a detection limit for maltose at 46.67 µM. In addition, the selectivity of maltose was checked in the presence of starch and after its hydrolysis with α-amylase. Compared with the conventionally used dinitrosalicylic acid (DNS) colorimetric method, the proposed method could be applied to commercial fresh apple juice, watermelon, and honey to prove its viability for detecting RS in fruits; the total reducing sugar content was 287, 165, and 751 mg/g, respectively.

Abstract
Advanced platelet-rich fibrin (A-PRF) provides long-term release of growth factors that potentially accelerate wound healing. In this study, core-shell nanofibrous structure of polyvinyl alcohol (PVA) core and gelatin (Gel) shell containing A-PRF is fabricated through coaxial electrospinning method. PVA/(Gel/A-PRF) core-shell nanofibers had the highest porosity, specific surface area and hydrophilicity among all the studied nanofibers. PVA/(Gel/A-PRF) core-shell nanofibers with a tensile stress of 7.43 ± 0.38 MPa and an elastic modulus of 102.05 ± 9.36 MPa had higher mechanical properties than PVA/Gel/A-PRF and PVA/Gel blend nanofibers. PVA/(Gel/A-PRF) nanofibers had a 47.41 ± 1.97 % degradability over 7 days of immersion in PBS. The release of VEGF and PDGF-AB growth factors from PVA/(Gel/A-PRF) core-shell nanofibers and PVA/Gel/A-PRF blend nanofibers were evaluated. It was shown that L929 cell proliferation and adhesion on PVA/(Gel/A-PRF) core-shell nanofibers were significantly higher than other samples. Also, chicken chorioallantoic membrane (CAM) assay revealed that the highest angiogenic potential among the studied samples related to PVA/(Gel/A-PRF) sample. In vivo studies on a rat model showed wound closure for PVA/(Gel/A-PRF) group was 97.83 ± 2.03 % after 11 days. Histopathological and immunohistochemical examinations approved the acceleration of wound healing by PVA/(Gel/A-PRF) core-shell nanofiber dressing. The results strongly recommend the use of PVA/(Gel/A-PRF) core-shell nanofiber dressing for the repair of full-thickness wounds.

Abstract
Gelatin (GH) is a natural polymer material with unique physical, chemical, and biological properties that render it a good base material for biomedical material production. Herein, Ag nanoparticles (NPs) were loaded onto a waterborne polyurethane-GH composite (WPU-g-GH) to prepare a GH-based nanocomposite (AgNP/WPU-g-GH) films). The prepared nanocomposite films were characterized using several analyses including Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, X-ray diffraction, transmission emission microscopy, mechanical strength tests, and other analyses. The results demonstrated that the nanocomposite films had high mechanical strength, good thermal stability, and controllable biodegradability. In particular, when the AgNP loading content was 0.03%, the tensile strength, elongation at break, and average particle size of the nanocomposite film reached 45.13 MPa, 476.04%, and 13.02978 ± 1.64406 nm, respectively. Disk diffusion and cytotoxicity analyses revealed that the nanocomposite films exhibited significant antibacterial activity against Gram-negative and Gram-positive bacteria without affecting the cell viability of fibroblasts. These findings indicate that the nanocomposite films with high mechanical strength and antibacterial activity could be used for wound management, tissue adhesion, and biomaterial surface coating.

Abstract
The topical delivery offers numerous benefits, such as the ability to deliver drugs specifically on site selectively, prevents fluctuations in the levels of the drug, improved compliance, and improved self-medication capacity. Skin is the main route of the administration of the drug delivery system (DDS) and burns mainly cause skin damage. A burn is a kind of damage caused to skin and tissues by fire, ice, electrical energy, pollutants, friction, and radiation. There are three different types of burns, including superficial epidermis burns, partial-thickness dermis that stretch to the papillary and reticular dermis, and full-thickness burns that cover the dermis whole. The objective of the present review article is to focus on fabrication techniques of medical textiles, different types of polymers used for designing medicated textiles, skin burn conditions, and application of medicated textiles for treatment of burn along with other applications. Cream, ointment, and gel are the dosage forms used in burns. Intravenous fluids, wound care, assorted antibiotics, surgical and alternative medicines, burned creams and salami, dressings can be used to treat wounds. Nanofibers are nanometer-specific fibers that encapsulate drugs inside them and cure wounds. Nanofibers have all the properties that speed up wound healing. The properties are mechanical integrity, proper timing of wound addiction, temperature homeostasis facilitation and gas exchange, absorption of exudates. The nanofibers have been used in burn care and have been highly efficient and non-toxic.

Abstract
N-heterocyclic silver carbene compounds have been extensively studied and shown to be active agents against a host of pathogenic bacteria and fungi. By incorporating hypothesized virulence targeting substituents into NHC-silver systems via salt metathesis, an atom-efficient complexation process can be used to develop new complexes to target the passive and active systems of a microbial cell. The incorporation of fatty acids and an FtsZ inhibitor have been achieved, and creation of both the intermediate salt and subsequent silver complex has been streamlined into a continuous flow process. Biological evaluation was conducted with in vitro toxicology assays showing these novel complexes had excellent inhibition against Gram-negative strains E. coli, P. aeruginosa, and K. pneumoniae; further studies also confirmed the ability to inhibit biofilm formation in methicillin-resistant Staphylococcus aureus (MRSA) and C. Parapsilosis. In vivo testing using a murine thigh infection model showed promising inhibition of MRSA for the lead compound SBC3, which is derived from 1,3-dibenzyl-4,5-diphenylimidazol-2-ylidene (NHC*).

Abstract
A hybrid scaffold of gelatin-glycosaminoglycan matrix and fibrin (FGG) has been synthesized to improve the mechanical properties, degradation time and cell response of fibrin-like scaffolds. The FGG scaffold was fabricated by optimizing some properties of fibrin-only gel and gelatin-glycosaminoglycan (GG) scaffolds. Mechanical analysis of optimized fibrin-only gel showed the Young module and tensile strength of up to 72 and 121 KPa, respectively. Significantly, the nine-fold increase in the Young modulus and a seven-fold increase in tensile strength was observed when fibrin reinforced with GG scaffold. Additionally, the results demonstrated that the degradation time of fibrin was enhanced successfully up to 7 days which was much longer time compared to fibrin-only gel with 38 h of degradation time. More than 45% of FGG initial mass was preserved on day 7 in the presence of aprotinin. Human corneal fibroblast cells (HCFCs) were seeded on the FGG, fibrin-only gel and GG scaffolds for 5 days. The FGG scaffold showed excellent cell viability over 5 days, and the proliferation of HCFCs also increased significantly in comparison with fibrin-only gel and GG scaffolds. The FGG scaffold illustrates the great potential to use in which appropriate stability and mechanical properties are essential to tissue functionality.

Abstract
Electrospun fiber scaffolds have a huge potential for the successful treatment of infected wounds based on their unique properties. Although several studies report novel drug-loaded electrospun fiber-based biomaterials, many of these do not provide information on their interactions with eukaryotic and bacterial cells. The main aim of this study was to develop antibacterial drug-loaded porous biocompatible polycaprolactone (PCL) fiber scaffolds mimicking the native extracellular matrix for wound healing purposes. Mechanical property evaluation and different biorelevant tests were conducted in order to understand the structure-activity relationships and reveal how the surface porosity of fibers and the fiber diameter affect the scaffold interactions with the living bacterial and eukaryotic fibroblast cells. Cell migration and proliferation assays and antibiofilm assays enabled us to enlighten the biocompatibility and safety of fiber scaffolds and their suitability to be used as scaffolds for the treatment of infected wounds. Here, we report that porous PCL microfiber scaffolds obtained using electrospinning at high relative humidity served as the best surfaces for fibroblast attachment and growth compared to the nonporous microfiber or nonporous nanofiber PCL scaffolds. Porous chloramphenicol-loaded microfiber scaffolds were more elastic compared to nonporous scaffolds and had the highest antibiofilm activity. The results indicate that in addition to the fiber diameter and fiber scaffold porosity, the single-fiber surface porosity and its effect on drug release, mechanical properties, cell viability, and antibiofilm activity need to be understood when developing antibacterial biocompatible scaffolds for wound healing applications. We show that pores on single fibers within an electrospun scaffold, in addition to nano- and microscale diameter of the fibers, change the living cell-fiber interactions affecting the antibiofilm efficacy and biocompatibility of the scaffolds for the local treatment of wounds.

Abstract
There has been increased interest in the production of nanoparticles (NP) through green chemistry. This article used durian fruit shell aqueous solution that acts as a reductive preparation of silver NPs. The silver nanoparticles have a size of approximately 25 nm. The NP size uniformity was determined by the SEM and TEM analysis. X-ray diffraction technique was used to characterize crystalline silver nanoparticles face-centered cubic structure. XPS spectrum showed distinct silver peaks on the nanoparticles’ surface. An optical method that was based on surface plasmon resonance (SPR) was used to perform the green Ag NPs aqueous ammonia sensing study. Optical measurement facilitated the ammonia sensing study of Ag NPs that had been prepared. The study also investigated the performance of the optical sensor, thus adding validity to the study. Also, the research sought to determine how the concentration of ammonia in ammonia sensing affects the Ag NPs that had been obtained. The study observed a linear relationship with R2 as the correlation factor which was equal to 0.9831. This was observed from the ammonia concentration plot versus absorption ratio that suggested that there was a linear increase in absorption ratio with increase in ammonia concentration. The study significance is that the room temperature optical ammonia sensor can be used in future for medical diagnosis in the detection of low levels of ammonia in biological fluid like sweat, cerebrospinal fluid, saliva, plasma, or biological samples. This enhances the application of the technique in human biomedical applications.

Abstract
Background:
Gelatin electrospun fibers incorporated with extracted cardamom Essential
Oil (EO) were developed and characterized.
Materials & Methods:
The gelatin solutions were evaluated in terms of conductivity, morphology,
fourier transform infrared spectroscopy, and the effect of cardamom EO on the gelatin fibers. Cardamom
EO showed significant antioxidant activity with IC50 value of 5 μg/mL. The extract contained
several active components including Cyclohexene, 1-methyl-4-(1-methylethylidene) and
Eucalyptol (1.8-cineol) as the most abundant components.
Results:
The images of the scanning electron microscopy revealed formation of nanofibers from
gelatin solution with significant entanglement. Furthermore, discrete beads were appeared by
increasing the concentrations of cardamom EO in the gelatin fibers. Reduction in conductivity
parameter of EO solutions could explain the observed defects. The fourier transform infrared spectra
showed the formation of hydrogen bonds in gelatin fibers. The infrared as well as spectrophotometric
spectra confirmed that EO was effectively involved in electrospun fibers.
Conclusion:
In conclusion, gelatin –a natural biopolymer, incorporated with cardamom EO forms
smooth fabricated electrospun nanofibers.

Abstract
The present study focuses on fabrication and characterisation of porous composite scaffold containing hydroxyapatite (HAP), chitosan, and gelatin with an average pore size of 250-1010 nm for improving wound repair and regeneration by Electrospinning method. From the results of X-Ray Diffraction (XRD) study, the peaks correspond to crystallographic structure of HAP powder. The presence of functional group bonds of HAP powder, Chitosan and scaffold was studied using Fourier Transform Infrared Spectroscopy (FTIR). The surface morphology of the scaffold was observed using Scanning Electron Microscope (SEM). The Bioactivity of the Nano composite scaffolds was studied using simulated body fluid solution at 37 ± 1°C. The biodegradability test was studied using Tris-Buffer solution for the prepared nanocomposites [nano Chitosan, nano Chitosan gelatin, Nano based Hydroxyapatite Chitosan gelatin]. The cell migration and potential biocompatibility of nHAP-chitosan-gelatin scaffold was assessed via wound scratch assay and were compared to povedeen as control. Cytocompatibility evaluation for Vero Cells using wound scratch assay showed that the fabricated porous nanocomposite scaffold possess higher cell proliferation and growth than that of povedeen. Thus, the study showed that the developed nanocomposite scaffolds are potential candidates for regenerating damaged cell tissue in wound healing process.

Abstract
Infections, especially those caused by multi-drug resistant pathogens, result in serious problems in wound healing process. In this study, Zataria multiflora (ZM) essential oil, as a strong natural antimicrobial agent, is incorporated into poly (vinyl alcohol)-based nanofiber mats to fabricate a novel wound dressing. Different amounts of ZM essential oil (0, 2, 5 and 10% (v/v)) were incorporated into chitosan/poly(vinyl alcohol)/gelatin (CS/PVA/Gel) solutions and then were successfully electrospun into beadless and uniform fibers with 95 ± 14, 154 ± 27, 187 ± 40 and 218 ± 58 nm in diameters, respectively. The produced nanofiber mats (CS/PVA/Gel/ZM) were chemically crosslinked by glutaraldehyde vapor. The chemical compositions of ZM essential oil and nanofiber mats were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) and Fourier Transform Infrared Spectroscopy (FTIR), respectively. The antimicrobial activity of the CS/PVA/Gel/ZM nanofiber mats was determined by the AATCC100 method. The nanofiber mat loaded with 10% of ZM essential oil completely inhibited the growth of Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans after 24 h of incubation. Swelling investigations showed that the produced nanofibers have a substantial ability to take up water, in the range of 400-900%. Mechanical properties of the nanofiber mats were studied by tensile testing. Furthermore, they were found to be non-toxic by biocompatibility assays on mouse fibroblast (L929) cells. The obtained results have demonstrated that CS/PVA/Gel nanofiber mats, loaded with ZM essential oil, are promising alternatives to conventional wound dressings.

Abstract
The synthesis, characterization and application of biologically synthesized nanomaterials have become an important branch of nanotechnology. In the present study, we report the synthesis of silver nanoparticles from fresh leaf extract of Centella asiatica (LEC). UV-Vis spectrum for silver colloids contains a strong plasmon band near 425[Formula: see text]nm, which confirms the formation of nanoparticles. The experimental results show that the silver nanoparticles are formed easily in the extract at ambient temperature. The resulting silver nanoparticles (AgNPs) were in the spherical form and the average size of the nanoparticles was in the range from 3[Formula: see text]nm to 30[Formula: see text]nm. From the above silver nanoparticles, we were taken up to investigate the effects of various concentrations of AgNPs on growth, development and yield of peanut plants. The results of the present experiment showed that the optimized concentration of AgNPs of the good germination, growth and pod yield of peanut plant is 5[Formula: see text]ppm.

Abstract
In this study, chitosan/polyvinyl alcohol (PVA)/zeolite nanofibrous composite membrane was fabricated via electrospinning. First, crude chitosan was hydrolyzed with NaOH for 24h. Afterward, hydrolyzed chitosan solution was blended with aqueous PVA solution in different weight ratios. Morphological analysis of chitosan/PVA electrospun nanofiber showed a defect-free nanofiber material with 50:50 weight ratio of chitosan/PVA. Subsequently, 1wt.% of zeolite was added to this blended solution of 50:50 chitosan/PVA. The resulting nanofiber was characterized with field emission scanning electron microscopy, X-Ray diffraction, Fourier transform infrared spectroscopy, swelling test, and adsorption test. Fine, bead-free nanofiber with homogeneous nanofiber was electrospun. The resulting membrane was stable in distilled water, acidic, and basic media in 20 days. Moreover, the adsorption ability of nanofibrous membrane was studied over Cr (VI), Fe (III), and Ni (II) ions using Langmuir isotherm. Kinetic parameters were estimated using the Lagergren first-order, pseudo-second-order, and intraparticle diffusion kinetic models. Kinetic study showed that adsorption rate was high. However, the resulting nanofiber membrane showed less adsorption capacity at high concentration. The adsorption capacity of nanofiber was unaltered after five recycling runs, which indicated the reusability of chitosan/PVA/zeolite nanofibrous membrane. Therefore, chitosan/PVA/zeolite nanofiber can be a useful material for water treatment at moderate concentration of heavy metals.

Abstract
This paper focuses on the recent advances on radiolysis-assisted shape-controlled synthesis of noble metal nanostructures. The techniques and protocols for producing desirable shapes of noble metal nanoparticles are discussed through introducing the critical parameters which can influence the nucleation and growth mechanisms. Nucleation rate plays a vital role on the crystallinity of seeds while growth rate of different seeds' facets determines the final shape of resultant nanoparticles. Nucleation and growth rate both can be altered with factors such as absorbed dose, capping agents, and experimental environment condition to control the final shape. Remarkable physical and chemical properties of synthesized noble metal nanoparticles by controlled morphology have been systematically evaluated to fully explore their applications.
