Electrospun Co 3 O 4 nanoparticles and its methanol detection property

Abstract: PVA/Co3O4 beads-free nanofibers were prepared with PVA (polyvinyl alcohol) and cobalt(II) chloride hexahydrate (CoCl2⋅6H2O) as precursor solution by the electrospinning method. Structural studies of Co3O4 nanoparticles were analyzed with X-ray diffraction (XRD) studies and proved crystalline. Morphological studies were performed with a field emission scanning electron microscope (FESEM) characterization, which revealed that electrospun nanofibers were smoothly edged and randomly distributed along the substrate. The PVA/Co3O4 nanofibers were calcined to obtain nanoparticles in the one-dimension-like arrangement. Vapour sensing studies of Co3O4 nanoparticles were performed towards the detection of the pulmonary disease biomarkers. The sensing characteristics were analyzed at various temperatures ranging from room temperature to 350 °C and it was observed that Co3O4 nanoparticles showed a better response to methanol at 350 °C. At the operating temperature of 350 °C, Co3O4 nanoparticle sensing studies were performed towards 21–2094 ppm of methanol. Co3O4 nanoparticles showed good sensing characteristics with quick response and recovery time towards methanol vapour, which helps in the detection of pulmonary disease through an exhaled breath.

Study of Antibacterial and Anticancer Properties of bioAgNPs Synthesized Using Streptomyces sp. PBD-311B and the Application of bioAgNP-CNC/Alg as an Antibacterial Hydrogel Film against P. aeruginosa USM-AR2 and MRSA.

Abstract: Here, we report the extracellular biosynthesis of silver nanoparticles (AgNPs) and determination of their antibacterial and anticancer properties. We also explore the efficacy of bioAgNPs incorporated in cellulose nanocrystals (CNCs) and alginate (Alg) for the formation of an antibacterial hydrogel film. Streptomyces sp. PBD-311B was used for the biosynthesis of AgNPs. The synthesized bioAgNPs were characterized using UV-Vis spectroscopy, TEM, XRD, and FTIR analysis. Then, the bioAgNPs’ antibacterial and anticancer properties were determined using TEMA and cytotoxicity analysis. To form the antibacterial hydrogel film, bioAgNPs were mixed with a CNC and Alg solution and further characterized using FTIR analysis and a disc diffusion test. The average size of the synthesized bioAgNPs is around 69 ± 2 nm with a spherical shape. XRD analysis confirmed the formation of silver nanocrystals. FTIR analysis showed the presence of protein capping at the bioAgNP surface and could be attributed to the extracellular protein binding to bioAgNPs. The MIC value of bioAgNPs against P. aeruginosa USM-AR2 and MRSA was 6.25 mg/mL and 3.13 mg/mL, respectively. In addition, the bioAgNPs displayed cytotoxicity effects against cancer cells (DBTRG-0.5MG and MCF-7) and showed minimal effects against normal cells (SVG-p12 and MCF-10A), conferring selective toxicity. Interestingly, the bioAgNPs still exhibited inhibition activity when incorporated into CNC/Alg, which implies that the hydrogel film has antibacterial properties. It was also found that bioAgNP-CNC/Alg displayed a minimal or slow release of bioAgNPs owing to the intermolecular interaction and the hydrogel’s properties. Overall, bioAgNP-CNC/Alg is a promising antibacterial hydrogel film that showed inhibition against the pathogenic bacteria P. aeruginosa and MRSA and its application can be further evaluated for the inhibition of cancer cells. It showed benefits for surgical resection of a tumor to avoid post-operative wound infection and tumor recurrence at the surgical site.

A spotlight on alkaloid nanoformulations for the treatment of lung cancer

Abstract: Numerous naturally available phytochemicals have potential anti-cancer activities due to their vast structural diversity. Alkaloids have been extensively used in cancer treatment, especially lung cancers, among the plant-based compounds. However, their utilization is limited by their poor solubility, low bioavailability, and inadequacies such as lack of specificity to cancer cells and indiscriminate distribution in the tissues. Incorporating the alkaloids into nanoformulations can overcome the said limitations paving the way for effective delivery of the alkaloids to the site of action in sufficient concentrations, which is crucial in tumor targeting. Our review attempts to assess whether alkaloid nanoformulation can be an effective tool in lung cancer therapy. The mechanism of action of each alkaloid having potential is explored in great detail in the review. In general, Alkaloids suppress oncogenesis by modulating several signaling pathways involved in multiplication, cell cycle, and metastasis, making them significant component of many clinical anti-cancerous agents. The review also explores the future prospects of alkaloid nanoformulation in lung cancer. So, in conclusion, alkaloid based nanoformulation will emerge as a potential gamechanger in treating lung cancer in the near future.

Biologically Active Compounds and Use of Medicinal Plants in Treatment of Microbial Infections, Sources, Biological Action and Cellular Action

Abstract: Medicinal plants have been used with practical implementation of certain herbal great source of plant based flavonoids, antioxidants compounds. Medicinal plants were traditionally used for health care and serve as the bases for the emergence of modern medicine. They have possess the high quality of the extracts to evaluate their therapeutic efficacy for their pharmacological action. Large variety of medicinal plants have been used as aromatic purposes and hence valuate for aroma and pharmacological sectors. Medicinal plants snowed stronger binding to the proteins secreted by the parasitic worms thus inhibiting them to proliferate in the cellular tissues thus acting as main source of immunity booster to the living tissues against the dyspepsia, gastritis, hyperacidity, menorrhagia, diabetes. Saraca asoca also used as source of medicinal pant due to its to antibacterial activity because of its potential against the of multiple bacterial strains. Some of the medicinal plants acting as dual nature such as targeting the microbial proteins and peptides playing important role in the development of natural therapies. Nanoparticles based therapies can be utilized for treatment of infectious diseases.
