“…Chitosan-FA nanoparticle was formed by interaction between positive charge of the amino group in chitosan and cross-linker agent, sodium TPP, which has a negative charge. 14 The result showed that the chitosan-FA revealed a smaller size of particle compared to the nanoparticle prepared from chitosan as described in our previous research due to the addition of tween 80 during chitosan-FA NP preparation. The addition of folic group into chitosan polymer affected the molecular size of the polymer.…”

Chitosan had been successfully modified by conjugating with folic acid for specific delivery for an anticancer agent. The modified chitosan-folate (chitosan-FA) then prepared into a nanosize particle (NP) and loaded with the active substances, a combination of doxorubicin (DOX) and curcumin analog, 2,5-bis-(4-hydroxy,3,5-dimethyl benzylidene) cyclopentanone (Pentagamavunon-1, PGV-1). In this research, the cytotoxic activity of chitosan-FA NP containing the drugs against MCF-7 breast cancer cell was evaluated. The ionic gelation method was used for preparing of the chitosan-FA NP containing active substances. Physical characterization including particle size and zeta potential of the NP was analyzed using Particle Size Analyzer (PSA), whereas the encapsulation efficiency (EE) was analyzed using ultrafast liquid chromatography (UFLC). Anticancer activity of nanoparticles was carried out using the MTT method. The particle size obtained for chitosan-FA containing active substances was 111.8 ± 4.11 nm with the EE more than 75% for DOX and around 12% for PGV-1. The cytotoxic test with MTT assay showed that the DOX and PGV-1 loaded in chitosan-FA NP had anticancer activity against MCF-7 cells with IC50 value 25.8±2.55 µg/mL for DOX and 24.7±0.91 µg/mL for PGV-1 in combination.

The crystallized Cu1-xZnxFe2O4 ferrites nanocrystalline has been prepared at low-temperature combustion route to study as a novel friendly environmentally benign fuel. Five batches of spinel as Cux Zn1-xFe2O4 were synthesis by a self-combustion method using nitrates as salt. The phase composition, crystal intensity and the nanostructure characteristics were resolved by x-ray diffraction and scanning electron microscope can be observations. BET analysis to indemnification the specific surface area around 20-10 nm. The results show an announced decrease in the combustion temperature when Cu-and Zn-ferrites spinel are utilized as catalysts effect. The ferrites have tested catalytically in combustion reaction of hydrogen peroxide.

“…In this study, chitosan was used as a stabilizing agent on the surface of the silver nanoparticles to prevent agglomeration. In our previous study, it was found that chitosan added as a coating agent on the surface of nanoparticles was able to prevent agglomeration in a sample of iron oxide nanoparticles by decreasing the size of iron oxide clusters [42].…”

The synthesis of silver nanoparticles using plant extracts, widely known as a green synthesis method, has been extensively studied. Nanoparticles produced through this method have applications as antibacterial agents. Bacterial and viral infection can be prevented by use of antibacterial agents such as soap, disinfectants, and hand sanitizer. Silver nanoparticles represent promising hand sanitizer ingredients due to their antibacterial activity and can enable reduced use of alcohol and triclosan. This study employed silver nanoparticles synthesized using Kepok banana peel extract (Musa paradisiaca L.). Nanoparticle effectiveness as a hand sanitizer can be enhanced by coating with a biocompatible polymer such as chitosan. The characterization of silver nanoparticles was conducted using UV-Vis, with an obtained peak at 434.5 nm. SEM-EDX analysis indicated nanoparticles with a spherical morphology. Silver nanoparticles coated with chitosan were characterized through FTIR to verify the attached functional groups. Gel hand sanitizers were produced using silver nanoparticles coated with different chitosan concentrations. Several tests were undertaken to determine the gel characteristics, including pH, syneresis, and antibacterial activity. Syneresis leads to unstable gels, but was found to be inhibited by adding chitosan at a concentration of 2%. Antibacterial activity was found to increase with increase in chitosan concentration.
