In this study, iron oxide nanoparticles (Fe 2 O 3 NPs) were synthesized, characterized, and their antibacterial activity was determined using a low-cost and simple method. Method: In this paper, magnetic nanoparticles were synthesized by a physical method of pulsed laser ablation in a liquid medium with 600 mJ energy. Magnetic Fe 2 O 3 NPs were prepared by using a 1064 nm Nd-YAG laser and bombarding the [Formula: see text]-Fe 2 O 3 target in a deionized aqueous solution. An absorption spectrometer was used to study the optical properties and structures of nanoparticles, the prepared nanoparticles were analyzed using Fourier transform infrared (FTIR) spectroscopy. Besides, utilizing FESEM, the morphological and surface characteristics were examined. The antibacterial activity of Fe 2 O 3 NPs against several pathogenic Gram-positive and Gram-negative bacteria isolated from various human infection sites was investigated using a disk diffusion experiment with laser pulse lengths of (100 nm, 150 nm, 200 nm and 300 nm) with the same laser energy. Result: The results showed the success of this method as the first sign that can be inferred from the change in the color of the solution to prepare nanoparticles. Fe 2 O 3 NPs are mostly spherical in shape, with nano sizes ranging between 66.7 nm and 9.5 nm. The energy gap was found to be in the range of 1.79–2.39 eV for almost all nanoparticles prepared. Fe 2 O 3 NPs were formed in almost spherical surface morphology with regular size and shape. The results showed their effect on stopping the growth of bacteria of type E. coli maximum zone of inhibition of 20 mm and 19 mm of S. epidermidis, 18 mm of type S. mutans and 16 mm of P. aeruginosa. As a result, in this study, it was shown that Fe 2 O 3 NPs produced in water by laser ablation method can be used as antibacterial agents due to these properties.","PeriodicalId":14085,"journal":{"name":"International Journal of Nanoscience","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135514278","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}

When their function is discovered, many substances are added for medical uses. Herbs are known to contain a variety of organic substances. These crucial herbs are the main ingredients in many pharmaceutical and healthcare products. Traditional folk medical practices offer essential information for the extraction and creation of numerous medications and activities as well. The production of a few highly active pharmaceuticals is justified by the extraction and characterization of a variety of bioactive chemicals from green factories. This study uses quantitative analysis of ethyl acetate, ethanol, n-hexane, chloroform and aqueous extract along with established methodologies to assess the phytochemicals. Alkaloids, flavonoids, reducing sugars, proteins, amino acids, saponins, tannins, terpenoids and glycosides were discovered in the quantification and phytochemical screening results. Due to the presence of several phytochemical substances, the entire plant of Psychotria octosulcata W. A. Talbot demonstrated a diversity of medicinal potential. The cytotoxicity activity of the plant extracts was predicted using brine shrimp lethality assay (BSLA). The results showed that the shrimp in the ethanolic extract of Psychotria octosulcata W. A. Talbotare extremely hazardous in higher concentrations. Only 10 shrimps are discovered to be lethal at lowest concentrations even after 24 h. This can be due to the presence of bioactive substances.","PeriodicalId":14085,"journal":{"name":"International Journal of Nanoscience","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135823134","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}

Moreover, the structural and morphological properties of the n-PSi were analyzed by using XRD and AFM, FTIR and PL. XRD patterns of PSi show that the films are single-crystalline, with cubic structure. The major peak characteristics are allocated to plane (004). The atomic force microscope image and the distribution chart of the grains of the n-PSi displayed that the grain sizes were −8.98. FTIR is a powerful and easy-to-use technique to obtain the surface chemical state of PSi. The convenience results from the transparency of silicon for IR light and the high surface area. The basic features begin from the knowledge of the bondings to hydrogen, [Si–H], and to oxygen [Si–O]. The model calculations sometimes provide useful information in the assignment. By examining FTIR, the active bonds showed the formation of PSi. PL spectra were measured in the range of (600–900) nm, the emission peak for the fixed excitation wavelength at 500 nm, and spectral 1.78 eV and 1.24 eV. PSi is recognized as an attractive building block for photonic devices because of its novel properties including high ratio of surface to volume and high light absorption. We first report NIR and VIS (PDs) fabricated by PSi as a carrier collector and a photoexcitation layer.","PeriodicalId":14085,"journal":{"name":"International Journal of Nanoscience","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135824172","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}
