The polycondensation kinetics of silicic acid was measured cryoscopically in a temperature interval between 5 ◦C and 35 ◦C. Unlike polyamines such as polyallylamine, polylysine or polyarginine, catalitical amounts of Cytochrom c have a distinct retarding influence on the polycondensation kinetics. The Arrhenius analysis of the experimental reaction rates with and without Cytochrome c determines...
The sequestering ability of polyamines and aminoacids of biological and environmental relevance (namely, ethylenediamine, putrescine, spermine, a polyallylamine, a branched polyethyleneimine, aspartate, glycinate, lysinate) toward dimethyltin(IV) cation was evaluated. The stability of various dimethyltin(IV) / ligand species was determined in NaCl(aq) at t = 25 degrees C and at different ionic ...
11-Aminoundecanoic acid capped titanium dioxide (capped-TiO2) nanoparticles (63 ( 2 Å total diameter and 20-24 Å core diameter) and polyallylamine hydrochloride, PAH, have been layer-by-layer self-assembled onto precoated (by poly(diallyldimethylammonium chloride), PDDA, or PAH) substrates. The ultrathin S-PDDA(capped-TiO2/PAH)n (n ) 5, 10, 15) films have been characterized by absorption and su...
Gold nanoparticles coated with oppositely charged polyelectrolytes, such as polyallylamine hydrochloride and polystyrenesulfonate, were examined for potential inhibition of prion protein aggregation and prion (PrPSc) conversion and replication. Different coatings, finishing with a positive or negative layer, were tested, and different numbers of layers were investigated for their ability to int...
It is known that some plant polyphenols and alkaloids can act as effective photosensitisers of UV radiation. This phenomenon enhance both therapeutic side effects. Since there no information regarding curcuminoids on their ability to function photosensitisers, this work investigated the effect radiation cytotoxic curcumin, well its nanostructured forms, against keratinocytes HaCaT line cancer c...
