Aiming to contribute with this demand, the current study focused on the synthesis of mesoporous silica (MS) bio-adsorbents (MS1, MS2, MS3 and MS4) based on Santa Barbara Amorphous-15 (SBA-15) by a relatively simple and sustainable process using sodium silicate (SS) extracted from rice husk ashes (RHA) and Pluronic P123. Subtle and careful changes in the synthesis conditions resulted in MS samples with ordered pores and high specific surface area (<i>S</i><sub><i>BET</i></sub>), that is, 712 m<sup>2</sup> g<sup>−1</sup> (MS1), 838 m<sup>2</sup> g<sup>−1</sup> (MS2), 905 m<sup>2</sup> g<sup>−1</sup> (MS3) and 806 m<sup>2</sup> g<sup>−1</sup> (MS4), which are higher than other silicas also produced from RHA, indicating that our bio-adsorbents may exhibit superior pollutant adsorption capabilities. In that regard, various research reports the potential of MS to adsorb dyes, heavy metals, bacteria, pharmaceuticals and other pollutants in model systems. However, our proposal advanced in testing the adsorbent potential of these materials for two independent systems: (i) removal of methylene blue (MB) model dye from aqueous solutions and (ii) treatment of an industrial denim laundry effluent. Indeed, all MS bio-adsorbents were potentially efficient and reusable, but MS1 and MS2 exhibited higher adsorption capacities for MB dye (q<sub>e</sub> = 327.29 and 365.78 mg g<sup>−1</sup>, respectively) at pH 12.0. The investigation of the effect of ions and DFT calculations contributed to elucidating the interactions between MB dye and MS bio-adsorbents. In addition, our bio-adsorbents stand out by their excellent efficiency (~ 75%) in the remediation of an industrial effluent exclusively by adsorption. Among the produced bio-adsorbents, MS2 has shown a higher degree of mesoscopic order, well-ordered and open-ended pores with oval architecture and interconnected hollow channels, but both MS1 and MS2 displayed similar adsorption capacities normalized by total surface area, demonstrating to be promising and eco-friendly adsorbents for use in environmental remediation.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"32 1","pages":"27 - 46"},"PeriodicalIF":2.5,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphologies, sol–gel transition, chemical structure, and pH of the hydrogels are comprehensively studied under the variation in the initial loading BLE concentration. Release kinetics of the hydrogels are evaluated in different environmental conditions to determine the BLE release behavior and the suitable mathematical model.

The BLE release from the hydrogels is affected by pH, temperature, and the BLE loading concentration and is governed by a controlled diffusion following the Korsmeyer-Peppas model. The hydrogels release 50.91–60.29% of their initial loading content and the release solutions demonstrate potent antibacterial activity against <i>E. coli</i> and <i>S. aureus</i> evidenced by the inhibition rate of 70.67–99.94%. Moreover, the chitosan hydrogels encapsulating BLE are biodegradable with a remarkably high degradability of 76.92–79.74% after 14 days of exposure to lysozyme under simulated physiological conditions.

Additionally, a dual pH-responsive drug delivery platform was developed, which encapsulated both 5-Fluorouracil (5-FU) drug and DHBD@MOF prodrug within a hydrogel composed of carboxymethyl cellulose (CMC) and alginate (Alg.).

Upon swelling of the hydrogel in the intestine and colorectum at pH around 6.5–7.4, pH-sensitive C = N bonding of DHBD@MOF was cleaved at acidic colorectal cancer sites, activating the inactive prodrug. Furthermore, the hydrogel facilitated controlled release of DHBD and 5-FU in simulated gastric fluid (SGF) at different pH levels (1.2, 4.5, 7.4, and 6.5). The gradual release of DHBD from hydrogel in the intestine (pH 7.4, 8.5 h) and colorectum (pH 6.5, 24 h) was 10.60% and 41.68%, respectively. This allowed for significant accumulation of the inactive DHBD@MOF prodrug at acidic tumor sites, with 89.40% and 58.32% accessing the tumors after 8.5 h and 24 h, respectively. The findings of this research hold promise for applications in medical science and pharmaceutics after in vivo experiments.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"31 6","pages":"2193 - 2203"},"PeriodicalIF":2.5,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
