Experimentation of nanomedicine is labor-intensive, time-consuming, and requires costly laboratory consumables. Constructing a reliable mathematical model for such systems also challenging due to the difficulties in gathering sufficient number data points. Artificial neural networks (ANNs) are indicated as an efficient approach investigate cause-effect relationships predict output variables. He...
Introduction: Curcumin is a water-insoluble agent with some anticancer and antimicrobial effects; while, solubility is essential for a medicine to reach target cells. This study set out to use chitosan tripolyphosphate nanoparticles (CTN) for making curcumin water-soluble, and delivering the required dosage of it to target cells. ...
the chitosan nanoparticles used widely as a drug delivery systems recently. in the present study the echis carinataus snake venom loaded chitosan nanoparticles were prepared based on ionic gelation of tripolyphosphate and chitosan. the nanoparticles physicochemical characteristics, stability and biological activity of encapsulated venom were studied. the particles were spherical in shape and th...
Stability Constants of Metal Ion Complexes of Cyclopentadienyltris(diethylphosphito-P)cobaltate(l-),
Stabüity Constants, Metal Ion Complexes, Oxygen Tripod Ligand The formation of metal ion complexes ML(> and ML2(>+ of the oxygen tripod ligand L~ = cyclopentadienyltris(diethylphosphito-P)cobaltate(l-) with metal ions M — Li+, Na+, K+, Mg+, Ca+, Sr+, Ba+, Mn+, Co+, Ni+, Cu+, Zn+, Cd+, Hg+, Pb+, Ag+, and La has been studied by pH titration at 25 °C in 95/5 methanol/water solutions kept at an ion...
Chitosan/carrageenan nanoparticles: effect of cross-linking with tripolyphosphate and charge ratios.
Chitosan/carrageenan/tripolyphosphate nanoparticles were prepared by polyelectrolyte complexation/ionic gelation, the latter compound acting as cross-linker. The incorporation of the three components in the nanoparticle matrix was assessed by analytical techniques (FTIR, XPS and TOF-SIMS). Using chitosan/carrageenan nanoparticles as control, the effect of the cross-linker in the particles prope...
