Abstract
Collagen nanoparticles (collagen-NPs) are promising biological polymer nanoparticles due to their exceptional biodegradability and biocompatibility. Collagen-NPs were bio-fabricated from pure marine collagen using the cell-free supernatant of a newly isolated strain, Streptomyces sp. strain NEAA-3. Streptomyces sp. strain NEAA-3 was identified as Streptomyces plicatus strain NEAA-3 based on its cultural, morphological, physiological properties and 16S rRNA sequence analysis. The sequence data has been deposited under accession number OR501412.1 in the GenBank database. The face-centered central composite design (FCCD) was used to improve collagen-NPs biosynthesis. The maximum yield of collagen-NPs was 9.33 mg/mL with a collagen concentration of 10 mg/mL, an initial pH of 7, an incubation time of 72 h, and a temperature of 35 °C. Using the desirability function approach, the collagen-NPs biosynthesis obtained after FCCD optimization (9.53 mg/mL) was 3.92 times more than the collagen-NPs biosynthesis obtained before optimization process (2.43 mg/mL). The TEM analysis of collagen-NPs revealed hollow sphere nanoscale particles with an average diameter of 33.15 ± 10.02 nm. FTIR spectra confirmed the functional groups of the collagen, collagen-NPs and the cell-free supernatant that are essential for the efficient capping of collagen-NPs. The biosynthesized collagen-NPs exhibited antioxidant activity and anticancer activity against HeP-G2, MCF-7 and HCT116 cell lines. Collagen-NPs assessed as an effective drug loading carrier with methotrexate (MTX), a chemotherapeutic agent. The TEM analysis revealed that the average size of MTX-loaded collagen-NPs was 35.4 ± 8.9 nm. The percentages of drug loading (DL%) and encapsulation efficiency (EE%) were respectively 22.67 and 45.81%.

Abstract
Resveratrol has been found to exert protective effects in neurological disorders, including epilepsy. However, its poor bioavailability and difficulty in reaching the brain's targeted location reduce resveratrol's efficacy substantially. The side effects due to the higher concentration of drugs are another matter of concern. The objective of the present study is to propose solutions to these issues by encapsulating resveratrol in glutathione-coated collagen nanoparticles' core. The collagen nanoparticles increase the resveratrol's bioavailability, and glutathione helps in the passage of the encapsulated resveratrol to the target location in the brain. The concentration also substantially reduces due to resveratrol's encapsulation in glutathione-coated collagen nanoparticles. The encapsulated resveratrol is termed nanoresveratrol. The effectiveness of nanoresveratrol on epilepsy seizures was evaluated through histopathological examinations, ELISA tests, and qRT-PCR tests on the hippocampus of the kindled mice. The novelty of the present study thus lies in (i) the synthesis of nanoresveratrol using glutathione-coated collagen nanoparticles and (ii) the application of synthesized nanoresveratrol in the treatment of epilepsy. The study's outcome shows that nanoresveratrol has a favorable impact in reducing cognitive impairment in kindled mice, and it is more effective in controlling epilepsy seizures than resveratrol. The p-values of all the nanoresveratrol-given groups of mice (compared with the diseased group) were substantially smaller (∼10-4 to 10-2) than the significance level (0.05), indicating that the nanoresveratrol-given groups are significantly different from the diseased group, i.e., the nanoresveratrol has a significant effect on the mice. The concentration of resveratrol also decreases substantially in the proposed nanoformulation. It was observed that even 0.4 mg/kg of nanoformulation of resveratrol is performing better than 40 mg/kg of resveratrol.
