With these advantages, it can be a natural alternative to drug delivery systems used in cancer treatments. Therefore, the effects of bio-synthesized nanosilver on A549 lung cancer cells were investigated. The synthesized AgNPs were first confirmed in terms of color changes, absorbance in UV–Vis spectrophotometry, morphological appearance in scanning electron microscopy (SEM) analysis, and EDS. Visible blackish color development was noticed during the 1-h production period, with a rising peak recorded at 420 nm and an average size of 43 nm; highly triangular and quasi-spherical AgNPs were observed in the SEM images. The Fourier transform infrared spectroscopy (FTIR) confirmed that phenolic groups from plant extracts formed new chemical bonds with AgNPs. AgNPs were determined to be 280% more effective against <i>E. coli</i> and 85% against <i>S. aureus</i> bacteria, one of the ampicillin antibiotics. In the MTT test, different concentrations of AgNPs capped with <i>Cannabis sativa</i> extracts showed a 100% inhibitory effect at 375 μg mL<sup>−1</sup> against the A549 liver cancer cell line after 48 h of exposure. In this study, tests were performed only on A549 lung cancer cells. It revealed that AgNPs synthesized from extracts of <i>Cannabis sativa</i> seeds could be used as a potential candidate to develop nanomedicines for the treatment of lung cancer in the near future. It has been determined that treatment opportunities can be increased with studies on cells of different cancer diseases.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"19 4","pages":"2031 - 2043"},"PeriodicalIF":3.3,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138532042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this progress has been hindered by the functional homogeneity arising from the structural uniformity of the inverse-designed MPAs. In this paper, we address this limitation by designing reconfigurable MPAs (RMPAs) with three distinct structures and propose a residual parallel neural network (RPNN) that incorporates the optimized residual fully connected neural network (RFC-NN) for the inverse design of multifunctional MPAs. The trained RPNN accurately predicts the structural parameters and their corresponding absorption spectra with remarkable precision, yielding <i>R</i><sup>2</sup> values of 0.9981 and 0.9928, respectively. With this model, we successfully inverted the design of MPAs with three functions: broadband absorption, dual-band absorption, and triple-band absorption properties. A particularly noteworthy achievement was the realization of absorption bandwidth shifts using liquid crystal (LC) materials. Our RPNN showcases its proficiency in designing RMPAs with multifunctionality, all within a single network model. This marks a significant advancement over previous research methodologies.
