Inverse Miniemulsion Method for Synthesis of Gelatin Nanoparticles in Presence of CDI/NHS as a Non-toxic Cross-linking System
In this research, gelatin nanoparticles were synthesized via inverse miniemulsion method by employing a mixture of a water soluble carbodiimide (CDI) and N-hydroxysuccinimide (NHS) as a non-toxic cross-linking system. The gelatin nanoparticles were characterized for their size and size distribution, morphology and stability and were compared with those of nanoparticles cross-linked by glutarald...
متن کاملInvestigation of singlet oxygen reactivity towards propofol.
The reaction between the anaesthetic agent 2,6-diisopropylphenol (propofol, PPF) and singlet oxygen (1O2) has been investigated in aqueous solution by means of HPLC, GC, absorption spectroscopy and laser flash photolysis with infrared luminescence detection. The rate constants for the physical and chemical quenching of 1O2 by PPF (kPPF) are found to be 2.66 x 10(5) M(-1) s(-1) and approximately...
متن کاملSinglet oxygen induces oxidation of cellular DNA.
The aim of the present work was to evaluate the potential for (1)O(2) to induce oxidation of cellular DNA. For this purpose cells were incubated in the presence of a water-soluble endoperoxide whose thermal decomposition leads to the formation of singlet oxygen. Thereafter, DNA was extracted and the level of several modified DNA bases was determined by HPLC analysis coupled to a tandem mass spe...
متن کاملTowards an Optimal DNA-Templated Molecular Assembler
In DNA-templated synthesis, reactants are attached to DNA strands and complementary DNA strands are used to control the reaction towards a goal compound. This very general, simple, and still efficient approach has proven to be successful for the design of complex one-pot synthesis for a large variety of compounds. For a given goal compound many different synthesis plans may exist, and all of th...
متن کاملSinglet oxygen mediated DNA degradation by copper nanoparticles: potential towards cytotoxic effect on cancer cells
The DNA degradation potential and anti-cancer activities of copper nanoparticles of 4-5 nm size are reported. A dose dependent degradation of isolated DNA molecules by copper nanoparticles through generation of singlet oxygen was observed. Singlet oxygen scavengers such as sodium azide and Tris [hydroxyl methyl] amino methane were able to prevent the DNA degradation action of copper nanoparticl...
