Abstract Fibroin is a protein that has been extensively studied for biomedical application. In the present study, silk was dissolved in CaCl2-C2H5OH-H2O in order to obtain silk fibroin (SF) solution, and it was then lyophilized in freeze-dryer. The electrospinning of SF sponge was performed at different fibroin concentrations. SF nanofibers were modified by crosslinking PAMAM dendrimers to carboxylic-terminated

Abstract Lateral flow immunoassay (LFIA) is the most widely used platform of the point-of-care (POC) detection. Since the most important factor in deciding the results of this technique is the visual quality of the test, it should be at its optimum. To address this issue, the present study examines optimising critical parameters to improve the quality of LFIA performance. In this regard the penicillin-binding

SEM-EDX, FTIR, XRD, and BET analyses were performed to characterize these nanoparticles. The results indicated that the maximum adsorption capacity

Abstract In this article, we report a simple, effective, sensitive, non-toxic and environmentally friendly method for the detection of dopamine (DA). This method utilises the property of the self-polymerization of dopamine under alkaline conditions, and gets the concentration of dopamine by measuring the fluorescence intensity of polydopamine (PDA) nanoparticles. And this method only uses NaHCO3 to

In that view, we have studied the phytochemical reducibility of silver nitrate by making use of Calotropis Procera (Ait.) R. Br root extract, and based on its medicinal properties, an attempt was made

Abstract Polydiacetylene (PDA)-based liposome have been attractive as sensory platforms owing to their applicability in simultaneous detection of colorimetric and fluorogenic signals. As PDA show low quantum yield, gold nanoparticles (GNPs) were used to amplify the fluorescence of the PDA by localized surface plasmon resonance. In this study, positively and negatively surface charged GNPs at different

Abstract Herein, BNPs@Cur-Pd as a versatile and reusable nanocatalyst was successfully synthesized and used for C–C coupling reactions. The Suzuki, Heck and Stille coupling reactions with good to excellent yields were conducted with Pd. Also, the catalyst could be recycled and reused for several sequential runs without considerable Pd leaching or diminishing of reaction yields. This simple methodology

Abstract Every year, many people die due to cancer in all of the world. So, the preparation and formulation of new chemotherapeutic supplements and drugs with remarkable effects for the treatment of cancer are in the priority of both developing and developed countries. Recently, gold nanoparticles have been used as modern chemotherapeutic drugs for the treatment of several cancers such as leukemia

Abstract The present study deals with Plectranthus amboinicus (Lour.), multiple potential herbs perceived as a medicinal and culinary adjunct has been used to fabricate gold (Au) nanoparticles (NPs) in an eco-benign fashion. We have primly reported the antioxidant and anticarcinogenic effects of phytofabricated Au NPs towards lung adenocarcinoma (LAC) cells (A549 cell line) in vitro. The herbal concentrate

Abstract The design of highly active photocatalysts for degradation of phenol can be particularly challenging for solar energy utilisation. Herein, a series of mesoporousLaCo1−xCexO3catalysts have been synthesised and studied for degradation of phenol under UV irradiation. Compared with LaCoO3-SG catalyst which is formed through sol-gel method, optimised LaCo1−xCexO3-NC prepared by nanocasting method

Abstract In this article, the dynamic behaviour of a rectangular atomic force microscope immersed in different liquids has been investigated. To account the rotatory inertia and shear deformation effects, Timoshenko beam theory has been applied. Here carbon tetrachloride (CCl4), methanol, acetone, water and air have been considered as the environments. Euler–Bernoulli and Timoshenko beam theories has

Abstract Lung cancer is one of the most widely recognised types of cancer and the acquisition of resistance towards chemotherapeutic drugs worsens the situation. Therefore, a site-directed, multi-targeting drug delivery system that is compliant with patients is the need of the hour. 5-Fluorouracil (5-FU), an anti-cancer chemotherapy drug, was delivered to the lung cancer cells using papain-inspired

Abstract In this work, worm-like SnS2 nanoparticles were prepared by a hydrothermal process. And then their photocatalytic activity was explored for the restoration of effluent containing Cr (VI). The results indicate that the product obtained is hexagonal SnS2 nanoparticles and adopts a worm-like morphology with length of approximate 6 nm and diameter of 3 nm. Moreover, the as-prepared SnS2 nanoparticles

Abstract In this work, by appealing to a heterometallic cluster approach, a new highly porous metal-organic framework (MOF) formulated as {(Me2NH2)[Ni3K2(TZIA)3(H2O)3]·(DMF)4}n (1) has been fabricated by a solvothermal reaction of a bifunctional organic ligand 5-(1 H-tetrazol-5-yl)isophthalic acid (H3TZIA) with the Ni(II) and K(I) salts in water and DMF mixed solvents. The resulting activated 1a has

Abstract Mitotic spindle orientation is postulated to be regulated by two mechanisms: (1) Hertwig’s rule in which cells divide perpendicular to their major axis and (2) cortical cues arising from the spatial distribution of extracellular matrix. It was shown that cortical cues override cell geometry in dictating mitotic spindle orientation for cells cultured on 2D surfaces. In this study, we seek to

Bacterial adhesion and biofilm formation on surfaces raises health hazard issues in the medical environment. Previous studies of bacteria adhesion have focused on observations in their natural/native environments. Recently, surface science has contributed in advancing the understanding of bacterial adhesion by providing ideal platforms that attempt to mimic the bacteria's natural environments, whilst
