Abstract Calophyllum inophyllum is a tropical plant that could have useful medicinal properties for pharmaceutical and cosmetic applications. The present study extracted the flower, fruit, leaf, twig, and bark of the plant by maceration in different organic solvents. The correlation between bioactive compounds and their biological activities was investigated, with emphasis on their therapeutic relevance through in silico pharmacokinetic predictions using SwissADME. Qualitative and quantitative analyses were conducted to determine the total phenolic, flavonoid, and saponin contents of the extracts. Spectral analysis of the extracts revealed –OH, C=O, C=C, and C–H functional groups. The antioxidant activity of the… More > Graphic Abstract

Abstract SnSe powdered nanoparticles (NPs) are prepared using the co-precipitation method. The powdered NPs were studied using X-ray diffraction (XRD), UV-absorbance spectroscopy, and scanning electron microscopy (SEM) characterization techniques. The XRD result indicates that NPs are orthorhombic with a crystalline size of 4 nm for TS-1, 6 nm for TS-2, and 13 nm for TS-3, respectively. The SEM images show the surface morphology of the prepared NPs is not fully spherical, but semi-flower-like. The optical properties of the powdered NPs are found by UV-Vis absorbance spectroscopy, in which the highest absorbance was found between 200 nm More >

Abstract Peach gum polysaccharide (PGP), a readily available natural polysaccharide, boasts substantial potential across diverse applications, yet its practical utility is severely limited by its vulnerability to bacterial growth and limited antioxidant activity. Herein, we introduced a simple and effective method to enhance the antibacterial and antioxidant properties of PGP by conjugating it with salicylic acid (SA). Cytotoxicity evaluation results confirmed that the resulting PGP-SA retains the excellent biocompatibility of PGP. Notably, PGP-SA demonstrates outstanding antibacterial activity against both Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria, outperforming non-modified PGP. Its antibacterial mechanism is hypothesized to stem from… More > Graphic Abstract

Abstract This review systematically summarizes recent advancements in the design of antibacterial hydrogels and the surface-related factors influencing microbial adhesion to polymeric materials. Hydrogels, characterized by their three-dimensional porous architecture and ultra-high water content, serve as ideal platforms for incorporating antibacterial agents (e.g., metal ions, natural polymers) through physical/chemical interactions, enabling sustained release and enhanced antibacterial efficacy. For traditional polymers, surface properties (e.g., roughness, charge, superhydrophobicity, free energy, nanoforce gradients) play critical roles in microbial adhesion. Modifying the surface properties of polymers through surface treatment can regulate antibacterial performance. In particular, by referencing the micro/nanostructures found More >

Abstract The purpose of this research work is to determine the removal efficiency of Cu²⁺ and Pb²⁺ ions using polyvinyl alcohol/neem leaf extract/chitosan (PVA/NLE/CS) composite films as adsorbent materials from an aqueous medium, with respect to pH, contact time, and adsorbent dosage. The synthesized composite material was characterized using Fourier Transform Infrared (FTIR) spectroscopy, thermogravimetric analysis-Derivative Thermogravimetry (TGA-DTG), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDX). The antibacterial activity and swelling response of the material were studied using suitable methodologies. The FTIR study confirmed the interactions among PVA, chitosan, and… More >

Abstract The prolonged health monitoring using wearable technology faces challenges stemming from perspiration, including bacterial proliferation, compromised adhesion, signal quality deterioration, and user discomfort. Notably, excessive sweat fosters bacterial colonization, escalating infection risks, and compromising biomarker analysis. Existing antibacterial approaches, unfortunately, risk disrupting the delicate balance of skin microbiota. To address this, we’ve developed a Janus patch featuring Zn-Al layered double hydroxide (LDH) modification, which boasts sustained antibacterial properties while preserving the epidermal microecology. It integrates a hydrophobic LDH fabric that mechanically eradicate bacteria via a nanoknife effect, and a laser-engraved medical adhesive with microholes for More >

Abstract Background: The increasing incidence of cancers and infectious diseases worldwide presents a significant public health challenge that requires immediate intervention. Our strategy to tackle this issue involves the development of pharmaceutical formulations that combine phytopolyphenols (P), targeted drugs (T), and metal ions (M), collectively referred to as PTM regimens. The diverse pharmacological properties of PTM regimens are hypothesized to effectively reduce the risk factors associated with both cancers and infectious diseases. Methods: The effects of the pharmaceutical agents on the proliferation of cultured cancer cells and pathogens were assessed after 72 h and 48 h,… More >

Abstract This work uses GC-MS to analyze the bioactive compounds of Salvia rosmarinus essential oils (SREO) and evaluates their antibacterial, antifungal, and insecticidal effects, as well as the major component, 1,8-cineole. Chemical analysis identified 16 compounds accounting for 99.19% of the oil’s total content, with 1,8-cineole (33.17%), camphor (16.53%), α-pinene (14.46%), and camphene (8.14%) as the major constituents. Antimicrobial activities were assessed against pathogenic strains using minimal inhibit concentration (MIC) and minimum bactericidal concentration (MBC) assays. SREO exhibited a minimum MIC of 0.128% against P. aeruginosa, while 1,8-cineole showed a minimum MIC of 2.06% against the same strain,… More >

Abstract Juniperus oxycedrus (J. oxycedrus) is a traditional culinary spice and medicinal herb with a longstanding history of ethnopharmacological applications across diverse cultures. While prior research has explored the biological activities and phytochemical constituents of extracts derived from its leaves and seed cones, the present study systematically investigates their mineral and phenolic profiles alongside their multifunctional bioactive potential. Inductively coupled plasma-atomic emission spectroscopy (ICP-AES) analysis revealed a substantial abundance of essential macro- and microelements. Reversed-phase high-performance liquid chromatography (RP-HPLC) further identified high concentrations of phenolic acids (e.g., p-coumaric acid) and flavonoids (e.g., rutin and quercetin). The extracts exhibited More >
