Cellulose isolation was performed using a green method involving synergistic pretreatment with xylanase and laccase enzymes. This was followed by isolation of cellulose nanofibers (CNF) using mechanical process. The green pretreatment demonstrated high efficiency in delignification, reduced chemical usage, and increased whiteness index to 90.84 %. The fiber showed a high crystallinity index of 72.85 %, which was confirmed by wide-angle X-ray scattering (WAXS) analysis. Transmission electron microscopy (TEM) revealed CNF with an average diameter of 10.51 ± 2.41 nm. The crude extract showed anti-inflammatory effect and antimicrobial activities against <em>S. aureus</em> and <em>E. coli</em> with minimum bactericide concentration (MBC) of 51.6 mg/mL. The cytotoxicity of the extract was evaluated using MC3T3-E1 cell line. A novel multi-layered wound dressing was developed using the CNF and the extract. The chemical composition of the membrane was confirmed by Fourier transform infrared spectroscopy. The 3D structure of the membrane was established using Synchrotron radiation X-ray tomographic microscopy. The membrane is biodegradable, non-toxic against MC3T3-E1 cells and biocompatible with 78.52 % cell viability. These findings suggest the possibility of extracting valuable chemicals from agricultural wastes such as orchid stem using green pretreatment to create an eco-friendly wound dressing.</div></div>","PeriodicalId":37785,"journal":{"name":"OpenNano","volume":"22 ","pages":"Article 100229"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143150136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study was evaluated to investigate the therapeutic potential of biogenic selenium nanoparticles that was synthesized via <em>Lactbacillus plantarum (</em>L. <em>plantarum)</em> and <em>Lactbacillus casei (</em>L. <em>casei)</em> against colorectal cancer. The induction of colorectal cancer was carried out via a single dose (5 mg/kg) of 3-methyl-1, 2-dyhydrobenzo(j)aceanthrylene [3-MBA]. After that, animals were treated using 200 µl (from stock concentration 1.0 × 10⁹ CFUs per ml) of selenium nanoparticles derived from L. <em>casei</em> (SeNPs-Ca) or selenium nanoparticles derived from L. <em>plantarum</em> (SeNPs-P) as two separate treated groups for two weeks. Colorectal tumor induction declared a significant increment in total antioxidant capacity. Meanwhile, malondialdehyde level decreased upon 3-MBA intoxication. Molecular analysis of <em>Beclin1</em> as an autophagy signaling pathway revealed a remarkable reduction upon 3-MBA intoxication. Meanwhile, a significant overexpression was declared in both <em>EGFR</em> and <em>MMP-9</em> genes post 3-MBA-induced colorectal tumor. Furthermore, a remarkable alteration was recorded in the protein expression of both <em>p53</em> and <em>TNF-α</em> post 3-MBA injection. Both two treated groups of biogenic selenium nanoparticles declared a significant improvement in the measured parameters, with the superiority of SeNPs-Ca in modulating the altered biomarkers.

The World Health Organization emphasizes the need for effective prevention, early detection, and treatment strategies to address this public health challenge. Current treatment modalities, including surgery, hormonal therapy, immunotherapy, radiation therapy, and chemotherapy, are often associated with considerable side effects and high costs. This study investigates the biosynthesis of silver nanoparticles using <em>Acalypha indica L.</em> (AgNPs), a medicinal plant recognized for its therapeutic benefits, as a potential cancer treatment with minimal side effects and a lower risk of drug resistance. AgNPs exhibit anti-inflammatory properties and the ability to inhibit angiogenesis while counteracting drug resistance mechanisms. Moreover, the use of chitosan as a coating on AgNPs (AgNPs-Chit) enhances their stability and specificity toward cancer cells, thereby improving their anticancer efficacy. Characterization of the synthesized AgNPs was conducted using various techniques, including UV-Vis spectroscopy, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), particle size analysis (PSA), and transmission electron microscopy (TEM), confirming the successful synthesis, stability, and spherical morphology of the nanoparticles, with an average diameter of 7 nm and a zeta potential of −24.51 mV. In vitro cytotoxicity testing showed that AgNPs-Chit exhibited stronger anticancer activity against T47D cells with an IC₅₀ value of 173 µg/mL, compared to AgNPs (IC₅₀ 244 µg/mL) and the Acalypha indica L extract (IC₅₀ 826 µg/mL). When compared to the control, treatments with AgNPs-Chit, AgNPs, and the plant extract demonstrated statistically significant differences (∗<em>p</em> &lt; 0.05, ∗∗<em>p</em> &lt; 0.01).

This study aimed to enhance bilastine dissolution and patient compliance by formulating a nanosuspension-based orodispersible film (ODF). An anti-solvent precipitation method was employed to produce nanosuspension using different hydrophilic stabilizers (Soluplus®, Poloxamer 188, and PEG 6000). The influence of formulation parameters, such as the stabilizer ratio, the anti-solvent ratio, stirring speed, and the stabilizer type, on particle size and polydispersity index (PDI) was optimized using an experimental design approach. The optimal formulation, with a 1:1 stabilizer-to-drug ratio using Soluplus®, a 6:1 anti-solvent to solvent ratio, and a stirring rate of 820 rpm, yielded nanoparticles with a mean particle size of 83.8 nm and a narrow PDI of 0.019. This formulation also significantly enhanced the drug's dissolution rate in phosphate buffer pH 6.8, releasing 92.02% of bilastine within 90 minutes. Further characterization of the lyophilized nanoparticles using FESEM, FTIR, and XRD, confirmed their amorphous nature and drug compatibility. The optimized nanosuspension was subsequently incorporated into ODFs via the solvent-casting technique, with the optimal film formulated with a 1:1 ratio of PVA and HPMC E5 as the film-forming polymers, demonstrating a rapid disintegration time of 18 seconds and releasing 93.16% of bilastine within 6 minutes.
