Ultrasound-assisted synthesis of MIL-88(Fe) coordinated to carboxymethyl cellulose fibers: A safe carrier for highly sustained release of tetracycline

Preparation of NiFe2O4@MIL-101(Fe)/GO as a novel nanocarrier and investigation of its antimicrobial properties

“…Combinations of MOFs with NPs have been made due to their high adsorption capacity, easy functionality, and easy isolation with an external magnetic field. 24 There are many ways to improve and modify nanocarrier structures by adding a functional group and surface modification using different materials like PEG, 25 chitosan, 26 alginate, 27 carboxymethyl cellulose 28 and graphene oxide. 29 …”

Preparation and Evaluation of Aminomalononitrile-Coated Ca–Sr Metal–Organic Frameworks as Drug Delivery Carriers for Antibacterial Applications

“…The absorption band at 3308 cm –1 is attributed to the NH 2 moiety of TC, indicating the successful loading of TC onto the Ca–Sr–MOF structure. , Moreover, in the FTIR spectrum of TC–Ca–Sr–AMN–MOF, absorption bands are noted at approximately 1598 and 1451 cm –1 , which are attributed to CO and C–H vibrations, and an absorption band is noted at approximately 1024 cm –1 , which is attributed to the weak aliphatic amine bond (C–N) of AMN . The absorption band at 3345 cm –1 is attributed to the NH 2 moiety of TC, indicating the successful loading of TC onto the Ca–Sr–AMN–MOF structure. − Moreover, the FTIR spectrum results confirm the successful loading of TC onto Ca–Sr–MOF and Ca–Sr–AMN–MOF. As shown in Figure b, the characteristic maximum absorbances of TC are 297 and 363 nm, which are values similar to those in previous reports. , Moreover, the TC peaks of TC–Ca–Sr–MOF and TC–Ca–Sr–AMN–MOF are 295 and 357 and 294 and 357 nm, respectively, which are blue-shifted from the native TC peaks of 297 and 363 nm.…”

Visible-Light-Driven Photocatalytic Degradation of Tetracycline Using Heterostructured Cu2O–TiO2Nanotubes, Kinetics, and Toxicity Evaluation of Degraded Products on Cell Lines

“…Similar trends of dose-dependent toxicity of TC were described in other studies. 103 , 105 The degraded sample of each photocatalytic reaction performed in triplicates was used for toxicity testing against the selected cell lines. The toxicity percentage of TC and its degraded products showed a negative correlation [RAW 264.7: R 2 (−0.932), p -value (0.01) and THP-1: R 2 (−0.931), p -value (0.01)] with the degradation rate, and it confirmed the degradation of the antibiotic and loss of its activity ( Figure 10 B(i,ii)).…”

“…MTT assay was performed to determine the cytotoxicity of TC and degraded products as the absorbance data of the MTT assay were directly related to the viability of the active cells. , The MTT assay of native TC in triplicates of different concentrations (1, 10, 100, 250, 500, 1000, and 5000 μg/mL) on RAW 264.7 and THP-1 was used to test its toxicity. Bettany et al (1998) reported that TC causes apoptosis and cell death of mouse macrophage cell lines (RAW 264) …”
