Abstract
Humans often have bleeding, which exerts substantial selective pressure on the coagulation system to optimize hemostasis in a variety of situations. Uncontrolled hemorrhage due to severe trauma leads to morbidity and mortality. Although nonbiological surfaces such as silicates can activate coagulation factor XII (FXII), the presence of Zn (Zinc) in the material stimulates and activates the various steps in the coagulation cascade. This results in blood clotting. The Zn@SiO2 nanocomposite has an excellent hemostatic property that establishes hemostasis by activating the factors responsible for the formation of a stable clot called fibrin mesh. This can be used as a hemostatic agent during surgeries and in any other trauma condition related to bleeding. Zn@SiO2 was synthesized and characterized with XRD, FTIR and HRTEM. It is analyzed for its RBC (Red Blood Corpuscles) aggregation and Platelet adhesion ability, fibrin formation, thrombus formation and prothrombin time (PT), Activated Partial Thromboplastin Time (aPTT), D-dimer for its ability to activate the coagulation cascade to achieve stable clotting.

Abstract
Gastrointestinal cancers are one among the most frequently reported cancers where colorectal and gastric cancers ranks third leading cause of cancer related death worldwide. Phloroglucinol, a well-known therapeutic agent for cancer, where its usage has been limited due to its poor water solubility and bioavailability. Hence, our study aims to synthesize and characterize Hyaluronan grafted phloroglucinol loaded Mesoporous silica nanoparticles (MSN-PG-HA). Our nano-formulation hasn't shown any teratogenic effect on Zebrafish embryos, no hemolysis and toxic effect with normal fibroblast cells with a maximum concentration of 300 μg/mL. The cumulative drug release profile of MSN-PG-HA showed a maximum drug release of 96.9 % with 5 mM GSH under redox responsive drug release, which is crucial for targeting cancer cells. In addition, the MSN-PG-HA nanoparticles showed significant a cytotoxic effect against HCT-116, AGS and SW-620 with IC50 values of 86.5 μg/mL, 80.65 μg/mL and 109.255 μg/mL respectively. Also, the cellular uptake assay has shown an increased uptake of FITC-labeled-MSN-PG-HA by HA-receptor mediated endocytosis than FITC-labeled-MSN-PG without HA modification in CD44+ gastrointestinal cancer cell lines. The ability of MSN-PG-HA to target CD44+ cells was further exploited for its application in cancer stem cell research utilizing in silico analysis with various stem cell pathway related targets, in which PG showed higher binding affinity with Gli 1 and the simulation studies proving its effectiveness in disrupting the protein structure. Thus, the findings of our study with nano-formulation are safe and non-toxic to recommend for targeted drug delivery against gastrointestinal cancers as well as its affinity towards cancer stem cell pathway related proteins proving to be a significant formulation for cancer stem cell research.

Abstract
Patients and healthcare systems stand to gain much from the use of substances that can accelerate wound healing. In this research work, a polymeric patch was fabricated using polymers like poly (vinyl alcohol) (PVA) and Moringa oleifera gum (MO) incorporated with graphene oxide (GO) and naringin (Nar) (drug). This study determined the impact of using PVA/MO/GO/Nar polymeric patch on wound healing via in vitro and in vivo investigations. Graphene oxide was synthesized by modified Hummer's method. The synthesized sample was characterized using XRD, FT-IR, RAMAN Spectroscopy, FESEM and HRTEM. Antibacterial analysis of the GO on four different bacteria was studied through well diffusion, colony count, growth curve and biofilm assay. Biocompatibility was analysed by haemolysis assay. The morphology, antibacterial activity, haemolysis assay, swelling, degradation, porosity, water vapour transmission rate, drug release, blood pump model, in-vitro scratch assay and MTT assay were analysed for the fabricated polymeric patches under in-vitro condition. The PVA/MO/GO/Nar patch has shown enhanced wound healing in in-vivo wound healing experiments on albino Wistar rats.

Abstract
Hemorrhage stands out as a leading factor contributing to fatalities in trauma cases. Hemorrhage is associated with the process of hemostasis. Hemostasis is the primary stage of wound healing. Hydrogels can aid in hemostasis and minimize the duration of wound healing. Calcium is one of the clotting factors and is a key component for the activation of the coagulation cascade. In this work, we have developed a polymeric hydrogel matrix made up of κ-carrageenan and sodium alginate containing a calcium silica nanocomposite and a natural drug, namely the bark of L. coromandelica. The nanocomposite was characterized using various modalities such as XRD, FTIR, FESEM and HRTEM. The rheological and morphological properties of the pure and composite hydrogels were examined. The antimicrobial activity, hemocompatibility and hemostatic efficacy of the materials were studied using various in vitro assays including bacterial growth curve analysis, colony counting, anti-biofilm assay, hemolysis assay and in vivo clotting studies. The drug incorporated nanocomposite hydrogel exhibited superior activity in animal models.

Abstract
An open wound or sore on the bottom of the foot caused by diabetes is known as a diabetic foot ulcer. Preventive measures are essential, including consistent foot care and glycemic management. The dangers associated with diabetic foot ulcers can be reduced via early identification and timely treatment. The risk of foot ulcers and limb amputation increases with age and duration of diabetes. Quercetin contains anti-inflammatory and antioxidant properties. Furthermore, the calcium carbonate/silica (CaCO3/SiO2) nanocomposite has a good anti-inflammatory property due to the presence of calcium, which will aid in wound healing. As a result, combining quercetin (plant based anti-inflammatory drug) and CaCO3/SiO2 nanocomposite will boost the wound healing rate. We have synthesized CaCO3/SiO2 nanocomposite in sol-gel method and characterized using XRD, FTIR and TEM. Cell line tests and the MTT assay revealed that the PLGA/gelatin/CaCO3/SiO2/quercetin patch enhanced the proliferation of cells. Its anti-bacterial efficacy against four major bacterial strains often found in wound locations, as well as its water retention, make it an ideal material for diabetic wound healing. In-vivo trials confirms the enhanced diabetic wound healing potential of the patch.

Abstract
Bone is a unique nanocomposite tissue composed of organic and inorganic materials. Bone grafting is a common surgical method used to improve bone regeneration in dentistry and orthopedic surgery. Because standard therapies have substantial drawbacks, nanomaterials provide alternative options for bone repair. Owing to its high bioactivity, osteoconductivity, biocompatibility, and topography that matches the architecture of real bone, hydroxyapatite nanoparticles (n-HA) are commonly used in bone treatment. We report here the synthesis and characterization of Naringin (NA) functionalized n-HA using HRTEM, FTIR, XRD, and UV-visible spectroscopy. The obtained results indicated that the n-HA can be functionalized with Naringin and they might be used as a bone regenerative material in medical and dental fields.

Abstract
Wounds are a serious life threat that occurs in daily life. The complex cascade of synchronized cellular and molecular phases in wound healing is impaired by different means, involving infection, neuropathic complexes, abnormal blood circulation, and cell proliferation at the wound region. Thus, to overcome these problems, a multifunctional wound dressing material is fabricated. In the current research work, we have fabricated a wound dressing polymeric patch, with poly(vinyl alcohol) (PVA) and chitosan (Cs) incorporated with a photocatalytic graphene nanocomposite (GO/TiO2(V-N)) and curcumin by a gel casting method, that focuses on multiple stages of the healing process. The morphology, swelling, degradation, moisture vapor transmission rate (MVTR), porosity, light-induced antibacterial activity, hemolysis, blood clotting, blood abortion, light-induced biocompatibility, migration assay, and drug release were analyzed for the polymeric patches under in vitro conditions. PVA/Cs/GO/TiO2(V-N)/Cur patches have shown enhanced wound healing in in vivo wound healing experiments on Wister rats. They show higher collagen deposition, thicker granulation tissue, and higher fibroblast density than conventional dressing. A histological study shows excellent re-epithelialization ability and dense collagen deposition. In vitro and in vivo analysis confirmed that PVA/Cs/GO/TiO2(V-N) and PVA/Cs/GO/TiO2(V-N)/Cur patches enhance the wound healing process.

Abstract
Wound healing is a multi-stage process that is dynamic, interactive, and complicated. However, many nanomaterials are employed to expedite wound healing by demonstrating antibacterial activity or boosting cell proliferation. But only one phase is focused during the wound healing process. As a result, there is a need for optimum wound dressing materials that promotes different wound healing cascades with ideal properties. Herein, Graphene Oxide loaded with vanadium (V) doped titanium dioxide (TiO2) blended with chitosan, and polyvinyl alcohol (CS/PVA/GO/TiO2-V) patch was developed for wound healing. XRD, FTIR and FE-SEM analyses were carried out to study the morphology and structural property of the patch. The fabricated patch has a high surface porosity, excellent moisture vapor transfer rate, appropriate swelling behaviour, and oxygen permeability, which results in an excellent moist environment for wound breathing and effective management of wound exudates. The antibacterial test showed significant antibacterial efficacy against wound infections in the presence of light when compared to dark. In-vitro analysis such as hemocompatibility, cytotoxicity, cell adhesion, and scratch assay show the predicted potential wound healing application with high biocompatibility. These results suggest that CS/PVA/GO/TiO2-V patch provides a microenvironment favourable to cells' growth and differentiation and positively modulates full-thickness wounds' healing.

Abstract
Bone is an amazing nanocomposite tissue made of both organic (primarily collagen) and inorganic (primarily nano-hydroxyapatite [n-HA]) elements. Bone grafting is a widely used surgical technique in dental and orthopedic surgeries to enhance bone regeneration. In view of the significant drawbacks of traditional treatments, nanomaterials offer new strategies for bone regeneration. The HA with the chemical formula of Ca10(OH) 2(PO4) 6 is very identical to the inorganic portion of bone. Due to its high stability and minimal solubility, it is often used in orthopedic and dental procedures. Currently, n-HA, which facilitates the growth of new bone, has garnered considerable attention because of better bioactivity and bone integration ability when compared to porous HA. This review gives comprehensive insights related to n-HA structure, chemical composition, surface modification techniques, and their application in bone tissue engineering.

Abstract
The synergistic photoelectrochemical (PEC) technology is a robust process for the conversion of CO2 into fuels. However, designing a highly efficient UV-visible driven photoelectrocatalyst is still challenging. Herein, a plasmonic Ag NPs modified TiO2/RGO photoelectrocatalyst (Ag-TiO2/RGO) has been designed for the PEC CO2 reduction into selective production of CH3OH. HR-TEM analysis revealed that Ag and TiO2 NPs with average sizes of 4 and 7 nm, respectively, were densely grown on the few-micron-sized 2D RGO nanosheets. The physicochemical analysis was used to determine the optical and textural properties of the Ag-TiO2/RGO nanohybrids. Under VU-Vis light illumination, Ag-TiO2/RGO photocathode possessed a current density of 23.5 mA cm-2 and a lower electrode resistance value of 125 Ω in CO2-saturated 1.0 M KOH-aqueous electrolyte solution. Catalytic studies showed that the Ag-TiO2/RGO photocathode possessed a remarkable PEC CO2 reduction activity and selective production of CH3OH with a yield of 85 μmol L-1 cm-2, the quantum efficiency of 20% and Faradic efficiency of 60.5% at onset potential of -0.7 V. A plausible PEC CO2 reduction mechanism over Ag-TiO2/RGO photocathode is schematically demonstrated. The present work gives a new avenue to develop high-performance and stable photoelectrocatalyst for PEC CO2 reduction towards sustainable liquid fuels production.

Abstract
In the current study, the therapeutic potential of cerium oxide nanoparticles (nCeO2) was investigated in a human tau (htau) model of Alzheimer's disease (AD), using Drosophila melanogaster as an in vivo model. nCeO2 synthesised via the hydroxide-mediated approach were characterised using Fourier transform infrared (FTIR), transmission electron microscopy (TEM), X-ray diffraction (XRD) analyses and Raman spectroscopy. Characterisation studies confirmed the formation of pure cubic-structured nCeO2 and showed that the particles were spherically shaped, with an average size between 20 and 25 nm. The synthesised nCeO2 were then administered as part of the diet to transgenic Drosophila for one month, at 0.1 and 1 mM concentrations, and its effect on the biochemical levels of superoxide dismutase (SOD), acetylcholinesterase (AChE), and the climbing activity of flies were studied in a pan-neuronal model (elav; htau) of AD. Using an eye-specific model of htau expression (GMR; htau), the effect of nCeO2 on htau and autophagy-related (ATG) gene expression was also studied. Dietary administration of nCeO2 at a concentration of 1 mM restored the activity of SOD similar to that of control, but both concentrations of nCeO2 failed to modulate the level of AChE, and did not elicit any significant improvements in the climbing activity of elav; htau flies. Moreover, nCeO2 at a concentration of 1 mM significantly affected the climbing activity of elav; htau flies. nCeO2 also elicited a significant decrease in htau gene expression at both concentrations and increased the mRNA expression of key autophagy genes ATG1 and ATG18. The results therefore indicate that nCeO2 aids in replenishing the levels of SOD and tau clearance via the activation of autophagy.

Abstract
Lumican, an extracellular matrix protein avails wound healing by binding to ALK5 membrane receptor (TGF-beta receptor I). Their interaction enables epithelialization and substantiates rejuvenation of injured tissue. To enrich permanence of ALK5-lumican interaction, we employed graphene and graphene oxide co-factors. Herein, this study explicates concomitancy of graphene and graphene oxide with ALK5-lumican. We performed an in silico approach involving molecular modelling, molecular docking, molecular dynamics for 200 ns, DSSP analysis and MMPBSA calculations. Results of molecular dynamics indicate cofactors influential in altering bioactive site of lumican than ALK5. Similarly, MMPBSA calculations unveiled binding energy of apoenzyme as -108.09 kcal/mol, holoenzyme (G) as -79.20 kcal/mol and holoenzyme (GO) as -114.33 kcal/mol. This concludes graphene oxide lucrative in enhancing binding energy of ALK5-lumican in holoenzyme (GO) via coil formation of Lum C13 domain. In contrast, graphene reduced binding energy of ALK5-lumican in holoenzyme (G) modifying Lum C13 into beta sheets. MMPBSA residual contribution analysis of Lum C13 residues revealed binding energy of -13.9 kcal/mol for apoenzyme, -6.8 kcal/mol for holoenzyme (G) and -19.5 kcal/mol for holoenzyme (GO). This supports coil formation propitious for better ALK5-Lum interaction. Highest SASA energy of -21.05 kcal/mol of holoenzyme (G) assures graphene reasonable for improved ALK5-lumican hydrophobicity. As per the motive of the study, graphene oxide enriches permanence of ALK5-lumican. This provides counsel for plausible exploitation of lumican and graphene oxide as targeted/nano drug delivery system to reinstate acute wounds, chronic wounds, corneal wounds, hypertrophic scars and keloids in near future.

Abstract
Semiconducting nanoparticles with luminescent properties are used as detection probes and drug carriers in in-vitro and in-vivo analysis. ZnO nanoparticles, due to its biocompatibility and low cost, have shown potential application in bioimaging and drug delivery. Thus, ZnO/SiO2 core/shell nanoparticle was synthesised by wet chemical method for fluorescent probing and drug delivery application. The synthesised core/shell nanomaterial was characterized using XRD, FTIR, UV-VIS spectroscopy, Raman spectroscopy, TEM and PL analysis. The silicon shell enhances the photoluminescence and aqueous stability of the pure ZnO nanoparticles. The porous surface of the shell acts as a carrier for sustained release of curcumin. The synthesized core/shell particle shows high cell viability, hemocompatibility and promising florescent property. Graphical Abstract.

Abstract
Wound healing is a common issue in our day to day life. Our immune system repairs the damaged tissue by itself and its a time-consuming process. The GO/CuO nanocomposite (NC) was synthesized through the sol-gel method. XRD, FT-IR, Raman, and TEM analysis were used to analysis the physico-chemical properties of the sample. The GO/CuO patches were prepared using chitosan (Cs)/poly vinyl alcohol (PVA) due to its biocompatibility and biodegradable nature. The obtained patches showed better antimicrobial and wound healing property than recently reported materials. The GO/CuO NC plays a major part in angiogenesis process and in the synthesis, stabilization of extracellular matrix skin proteins. Thus, GO/CuO NC enhance the wound healing mechanism by increasing cell proliferation, antimicrobial property and rapid initiation of inflammatory. Moreover, the antimicrobial activity of CuO, GO, GO/CuO and GO/CuO patch were tested against bacteria causing wound infections. Cs/PVA patch and Cs/PVA/GO/CuO patch were analyzed for swelling, evaporation and degradation behavior. Increase in cell viability and migration of NIH3t3 cells by NC patch shows a potential way for wound healing applications.

Abstract
Nowadays, graphene-based materials are receiving a great interest in the scientific community. The present work describes a novel method of synthesis of reduced graphene oxide (rGO). The Graphene oxide (GO) was prepared using a modified Hummers method. The GO was then reduced using the aqueous extract of Zingiber officinale and Brassica nigra by refluxing method. The reduction of GO was observed by changes in color from dark brown to black and then confirmed using UV-Visible spectral analysis. Surface Plasmon resonance for GO, Z-rGO and B-rGO were observed at 224[Formula: see text]nm, 344[Formula: see text]nm and 339[Formula: see text]nm, respectively. The morphology of the synthesized rGO were analyzed by scanning microscope. The stretching and vibrational mode were studied using FTIR analysis. The physical nature of the GO and rGO were examined using XRD. The synthesis of graphene using phytoextract as a reducing agent involves the simplistic and environmentally friendly approach.

Abstract
Ovarian cancer continues to be the most lethal among gynecological malignancies and the major cause for cancer-associated mortality among women. Limitations of current ovarian cancer therapeutics is highlighted by the high frequency of drug-resistant recurrent tumors and the extremely poor 5-year survival rates. Zinc oxide nanoparticles (ZnO-NPs) have shown promise in various biomedical applications including utility as anti-cancer agents. Here, we describe the synthesis and characterization of physical properties of ZnO-NPs of increasing particle size (15 nm - 55 nm) and evaluate their benefits as an ovarian cancer therapeutic using established human ovarian cancer cell lines. Our results demonstrate that the ZnO-NPs induce acute oxidative and proteotoxic stress in ovarian cancer cells leading to their death via apoptosis. The cytotoxic effect of the ZnO-NPs was found to increase slightly with a decrease in nanoparticle size. While ZnO-NPs caused depletion of both wild-type and gain-of-function (GOF) mutant p53 protein in ovarian cancer cells, their ability to induce apoptosis was found to be independent of the p53-mutation status in these cells. Taken together, these results highlight the potential of ZnO-NPs to serve as an anti-cancer therapeutic agent for treating ovarian cancers independent of the p53 mutants of the cancer cells.

Abstract
Wound healing is a complex multistep process. Wound healing materials should have good antibacterial activity against wound infection causing microbes. Curcumin has effective antimicrobial activity, anti-inflammatory and antioxidant property. Titanium dioxide (TiO2) is a biocompatible, nontoxic material used for many biomedical applications. The Usage of curcumin tagged TiO2 nanoparticles for wound healing activity is promising due to the properties of both curcumin and TiO2. We have synthesized curcumin tagged TiO2 nanoparticles. The synthesized materials are characterized with XRD, FTIR and TEM. TiO2-Cur nanocomposite was incorporated into poly vinyl alcohol (PVA) and sodium alginate (SA) patch. The PVA/SA/TiO2-Cur patch was prepared by gel casting method. Antibacterial efficiency of PVA/SA/TiO2-Cur patch was analyzed. Further, in vivo studies conducted on Wister rats confirmed the enhanced wound healing property of the PVA/SA/TiO2-Cur patch. Our results suggest that this could be an ideal biomaterial for wound dressing applications.

Abstract
Bone tissue engineering (BTE) relies on biocomposite scaffolds and bioactive molecules for bone regeneration. The present study was aimed to synthesize and characterize biocomposite scaffolds containing chitosan (CS), nano-hydroxyapatite (nHAp) and nano‑zirconium dioxide (nZrO2) along with microRNA (miRNA) for BTE applications. miRNAs act as post-transcriptional regulator of gene expression. The fabricated biocomposite scaffolds were characterized using SEM, FT-IR and XRD analyses. The effect of a bioactive molecule (miR-590-5p) with scaffolds was tested for osteoblast differentiation at the cellular and molecular levels using mouse mesenchymal stem cells (C3H10T1/2). The results showed that CS/nHAp/nZrO2 scaffolds promoted osteoblast differentiation, and this effect was further increased in the presence of miR-590-5p in C3H10T1/2 cells. Thus, we suggested that CS/nHAp/nZrO2 scaffolds with miR-590-5p would have potential towards the treatment of bone defects.

Abstract
Food preservation is an important field of research. It extends the shelf life of major food products. Our current study is based on food preservation through TiO2 and ZnO nanoparticles. TiO2 and ZnO are biocompatible nanomaterial. The biocompatibility of the materials were established through toxicity studies on cell lines. Titanium dioxide and Zinc Oxide nanoparticle were synthesized by wet chemical process. They are characterized by X-Ray diffraction and TEM. The antibacterial activities of both the materials were analysed to ensure their effectiveness as food preservative against Salmonella typhi, Klebsiella pneumoniae and Shigella flexneri. The results indicates that TiO2 and ZnO nanoparticle inhibits Salmonella, Klebsiella and Shigella. The mode of action is by the generation of ROS in cases of Salmonella, Klebsiella. Mode of action in Shigella is still unclear. It was also proved that TiO2 and ZnO nanoparticle are biocompatible materials.

Abstract
Targeted drug delivery using nanocrystalline materials delivers the drug at the diseased site. This increases the efficacy of the drug in killing the cancer cells. Surface modifications were done to target the drug to a particular receptor on the cell surface. This paper reports synthesis of hydroxyapatite and titanium dioxide nanoparticles and modification of their surface with polyethylene glycol (PEG) followed by folic acid (FA). Paclitaxel, an anticancer drug, is attached to functionalized hydroxyapatite and titanium dioxide nanoparticles. The pure and functionalised nanoparticles are characterised with XRD, TEM and UV spectroscopy. Anticancer analysis was carried out in DEN induced hepatocarcinoma animals. Biochemical, hematological and histopathological analysis show that the surface modified paclitaxel attached nanoparticles have an higher anticancer activity than the pure paclitaxel and surface modified nanoparticles without paclitaxel. This is due to the targeting of the drug to the folate receptor in the cancer cells.

Abstract
The pure hydroxyapatite (HAP) nanoparticles (NPs) have been synthesized by wet chemical precipitation method. Raman spectral measurements have been made for pure HAP, pure Polyethylene glycol (PEG) 6000 and PEG coated HAP in different mass ratios (sample 1, sample 2 and sample 3). The peaks observed in Raman spectrum of pure HAP and the XRD pattern have confirmed the formation of HAP NPs. Vibrational modes have been assigned for pure HAP and pure PEG 6000. The observed variation in peak position of Raman active vibrational modes of PEG in PEG coated HAP has been elucidated in this work, in terms of intermolecular interactions between PEG and HAP. Further these results suggest that the functionalization of nanoparticles may be independent of PEG mass.

Abstract
Hydroxyapatite is a bioceramic which has a wide range of medical application for bone diseases. To enhance its usage, we have prepared ciprofloxacin loaded nano hydroxyapatite (HA) composite with a natural polymer, alginate, using wet chemical method at low temperature. The prepared composites were analyzed by various physicochemical methods. The results show that the nano HA crystallites are well intact with the alginate macromolecules. For the composite system FT-IR and micro Raman results are reported in this paper. Studies on the drug loading and drug release have been done. The drug is pre-adsorbed onto the ceramic particle before the formation of composite. The thermal behavior of composite has been studied using thermo gravimetric analysis (TGA). This work, reports that the nanocomposite prepared under optimum condition could prolong the release of ciprofloxacin compared with the ciprofloxacin loaded hydroxyapatite.

Abstract
In bone disorders infections are common. The concentration of majority of antibiotics is very low in the bone tissue. A high local dose can be obtained from the ciprofloxacin-loaded hydroxyapatite nanoparticles. The present study is aimed at developing the use of hydroxyapatite and zinc-doped hydroxyapatite nanoparticles as a carrier for ciprofloxacin drug delivery system. The ciprofloxacin-loaded hydroxyapatite and zinc-doped hydroxyapatite have a good antibacterial activity against Pseudomonas aeruginosa and Staphylococcus aureus. Hydroxyapatite and zinc-doped hydroxyapatite were prepared and characterized using X-ray diffraction, Transmission electron microscopy and inductively coupled plasma optical emission spectrometry. They were loaded with ciprofloxacin using optimized drug loading parameters. Drug loading, in vitro drug release and antimicrobial activity were analyzed. The influence of zinc on the controlled release of ciprofloxacin was analyzed. The results show that the presence of zinc increases the drug release percentage and that the drug was released in a controlled manner.
