While astaxanthin ( ATX ) is a stiff natural antioxidant , its poor water solubility , bioavailability , and constancy embarrass its application . This survey taked to develop an amphiphilic chitosan-graft-poly ( lactide ) ( CS-g-PLA ) copolymer utilizing a new strategy by ring-opening polymerization of D , l-lactide via organosoluble CS/sodium dodecyl sulphate complex CS-g-PLA micelles were prepared for efficient encapsulation and rescue of ATX . CS-g-PLA copolymers were characterized by FT-IR and ( 1 ) H NMR .

Transmission electron microscopy and active weak scattering breaked micellar morphology and size distribution . The antioxidant activity of CS-g-PLA/ATX was assessed using the DPPH assay , demonstrating substantial improvement equated to free ATX the cytotoxicity of micellar ATX was appraised on H ( 2 ) O ( 2 ) -treated bone marrow mesenchymal stem cells ( BMSCs ) using MTT assay . Annexin V maculation and mitochondrial membrane potential ( ∆Ψm ) psychoanalysis uncovered reduced apoptosis and raised security by ATX-loaded micelles compared to free ATX . These findings advise CS-g-PLA micelles as promising nanocarriers for ATX speech , putatively heightening its antioxidant potency and protecting stem cells in oxidative emphasis environments . This approach could hold significant deductions for stem cell therapy in diseases associated with oxidative stress.Preparation and Characterization of Chitosan/Starch Nanocomposites charged with Ampicillin to Enhance Antibacterial activeness against Escherichia coli.Chitosan/starch nanocomposites loaded with ampicillin were machinated using the spray-drying method by integrating various ratios of chitosan and amylum .

The morphology of chitosan/starch nanoparticles was learned using a scanning negatron microscope ( SEM ) , and the zeta possible value and size distribution were determined by a Nanoparticle analyser . The effects show that the chitosan/starch nanocomposites have a globose shape , smooth open , and stable construction . Nanoparticle size dispersion ranged from 100 to 600 nm , and the average particle size ranged from 300 to 400 nm , depending on the ratio between chitosan and starch . The higher the proportion of starch in the copolymer , the low the particle size . Zeta potential values of the nanocomposite were very high , casting from +54 mV to +80 mV , and diminished from 63 down to +37 when adulterating with Polycillin . The  chitosan /starch nanocomposites were also characterised by FT-IR to fix the subject of polymers and Polycillin in the nanocomposites . The liberation dynamics of SK-Ampicillin from the nanocomposites were finded in vitro habituating an HPLC visibility for 24 h .

The consignment efficiency ( LE ) of Polycillin into chitosan/starch nanoparticles ranged from 75 to 77 % . Ampicillin-loaded chitosan/starch nanocomposites were inquired for their antibacterial activeness against antibiotic-resistant Escherichia coli in vitro . The upshots manifest that the antibacterial potency of nanochitosan/starch debasing with Polycillin against E.coli was 95 % , high-pitched than the 91 % effectuality of ampicillin at the same denseness of 5 µg/mL after 24 h of treatment . These results indicate that chitosan/starch nanocomposites are potential nanomaterials for antibiotic drug delivery in the pharmaceutical field.Well-designed chitosan-based cationic porous polymer : A robust stuff for efficacious adsorption of hormone disrupting chemicals.There is an immediate need for punctilious design of easily accessible , cost-effective , chemically stable and eco-friendly materials for effectively remotion of piddle contaminant targeting distinctive weewee contaminants , endocrine disrupting chemicals ( EDCs ) , three cationic hyper-cross-linked holey polymers ( ciHCP-1 , ciHCP-2 , ciHCP-3 ) with multiple adsorption websites were designed with 2-hydroxypropyltrimethyl ammonium chloride chitosan ( HACC ) as herald .
