Additionally, the as prepared finishing exhibited a considerable level of wash durability as a maximum reduction of pHRR by 17% was retained even after 5 washing cycles. A capsular polysaccharides (CPS) producer Bacillus velezensis SN-1 (B. velezensis SN-1) was isolated in Da-jiang, China. We used ultrasonic extraction to obtain CPS from a culture of B. velezensis SN-1 at a yield of 755 mg/L. Using gel permeation chromatography (GPC), CPS was separated into a single peak with a molecular weight of 1.46 × 105 Da. Its structures were characterized by gas chromatography (GC), methylation, Fourier transform infrared spectroscopy (FTIR), and nuclear magnetic resonance (NMR). The CPS was identified as a polysaccharide with a highly branched main chain of mannose with (1 → 3) connections. Moreover, our results revealed that CPS has the capacity to scavenge DPPH radical, hydroxyl radical, ABTS radical and oxygen radical in a manner that relied on concentration. Anti-neoplastic analysis showed that CPS displayed significant anti-tumor activity towards HepG-2 tumor cells. Above findings indicate that CPS generated by B. velezensis SN-1 may be adapted for use as a natural antioxidant in foodstuffs and as an anti-tumor drug. V.This study aimed to design and development of a magnetic natural hydrogel based on alginate (Alg), gelatin (Gel), and Fe3O4 magnetic nanoparticles (MNPs) as an efficient and "smart" drug delivery system (DDS) for cancer therapy. First, Alg was partially oxidized (OAlg), and then the Alg-Gel chemical hydrogel was synthesized through "Shift-Base" condensation reaction. Afterward, Fe3O4 NPs were incorporated into the hydrogel through in situ chemical co-precipitation approach. The scanning electron microscopy (SEM) image exhibited that the fabricated Alg-Gel hydrogel has porous microstructure without microphase separation. Transmission electron microscopy (TEM) revealed the well-defined f
