There is urgent need to develop suitable methods to produce antibacterial materials in large quantity and develop materials which have antibacterial properties. In this regard, we worked to prepare a composite of silver loaded zeolite and studied its applicability as antibacterial material. Zeolite beads loaded with different concentrations of silver was prepared and characterized using various techniques like SEM, FTIR, BET, AFM etc. For studying its antibacterial property, E. coli (gram negative) and S. aureus (Gram positive) microorganisms were used as model system. In antibacterial study, it was observed that silver loaded zeolite has antibacterial property against both E. coli (gram negative) and S. aureus (Gram positive) microorganisms.","PeriodicalId":286628,"journal":{"name":"Nanomedicine & Nanotechnology Open Access","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136206891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And a systematic study of their structural and magneto-optical properties were investigated. The proper deposition potentials of Co, and Cu were obtained from the cyclic voltammetry method. It was observed that the easy axis direction of magnetization was parallel to the film plane for all films. The X-ray diffraction (XRD) results revealed that all films had a mixture of hexagonal close-packed (hcp) and face centered cubic (fcc) phases. The Scanning electron microscope images (SEM) and atomic force microscopy (AFM) showed some parallelepiped and ellipsoid shaped rods with an averaged dimension about of 600 nm length, 600 nm width and 200 nm thickness for a sample electrodeposited at room temperature. These rods are irregularly arranged. Their irregular arrangement could explain the large d-spacing in the sample at this temperature. The magnetic analysis of the granular thin films alloys showed the saturation magnetization increased and the coercivity decreased as the deposition time increased. These results showed that the changes in magnetic and structural properties of granular cobalt/copper alloys deposits were substantially depending on the variation of deposition time. Therefore, the change of the deposition time was seen to control the properties of the alloys deposits and hence their properties could be modified for desired purpose.","PeriodicalId":286628,"journal":{"name":"Nanomedicine & Nanotechnology Open Access","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herbal compounds offer limited toxicity, high biocompatibility with numerous health benefits. The herbal drugs show many health benefits due to their presence of bioactive compounds in it. However, bioactive compounds suffer due to their poor solubility, poor bioavailability and stability. Niosomes, a non-ionic surfactant vesicle, can be a promising aspect to deliver the bioactive compound to enhance the bioavailability and stability. Niosomes have many advantages as it enables encapsulation of either hydrophilic and hydrophobic compounds. Preparation methods of niosomes are also simple and inexpensive. Moreover, encapsulating bioactive compounds in niosome not only improve the bioavailability but also enable it for sustained release or controlled release drug delivery. The review highlights various methods for niosome preparation, including thin-film hydration, reverse-phase evaporation, ether injection, microfluidization and bubble methods along with their advantages and disadvantages. Additionally, the characterization techniques, such as size determination, zeta potential measurement, and morphological evaluation, are also discussed.","PeriodicalId":286628,"journal":{"name":"Nanomedicine & Nanotechnology Open Access","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136208186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Clinical Example of Effective use of Biocompatible Magnetite (Fe3O4) Nanoparticles in the Complex Treatment of Multiple Sclerosis","authors":"Andrey Belousov","doi":"10.23880/nnoa-16000230","DOIUrl":"https://doi.org/10.23880/nnoa-16000230","url":null,"abstract":"Multiple Sclerosis (MS) is a multifactorial disease characterized by a variety of pathogenic mechanisms and pathways. Successful treatment of multiple sclerosis requires a fundamentally new approach in solving a number of problems related to the pathogenesis of the disease. Currently, nanotechnology opens a new stage of innovative medicine. Previously accumulated clinical experience in the use of biocompatible magnetite (Fe3 O4 ) nanoparticles, the study of their mechanisms of action on biological environments and systems of the living organism creates the preconditions for their effective use in the complex therapy of MS. The primary purpose of the study was to slow down the progression of MS, improve the neurological status and general condition of the patient, reduce the dynamics of demyelinating foci in the brain by including biocompatible Micromage-B magnetite nanoparticles in the complex therapy. Following the application of Micromage-B nano-particles in the treatment of MS, objective improvement of the neurological state, reduction of stiff-ness and rapid fatigue of the lower extremities were observed. Improved gait and coordination, de-creased trembling of the hand, depression and signs of concentration disorders gone, appetite re-stored, speech improved. During the entire period of use of Micromage-B, positive dynamic normalization of the neurological condition was observed. After six months, the total score fell from 210 to 45. The EDSS Disability Scale score has decreased from 6.0 to 5.0. Examination of the brain by MRI with contrast enhancement for the first time showed a decrease in the number of new foci of demyelinating in the brain. The procedure of restoration of the central nervous system activity in MS is due not only to the immunosuppressive properties of magnetite nanoparticles, but probably also to the activation of remyelination mechanisms and differentiation of oligodendrocytes due to enzymatic methylation. Considering the above, the use of biocompatible nanodevices in the complex treatment of MS is a promising innovative area and claims to be further considered for the purpose of subsequent inclusion of nanotechnology in the protocols for MS treatment.","PeriodicalId":286628,"journal":{"name":"Nanomedicine & Nanotechnology Open Access","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136208388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
