Developing Solutes as Quantitative Probes of Protein and DNA Processes

Dispersive liquid-liquid microextraction using silver nanoparticles as electrostatic probes for preconcentartion and quantitative analysis of terazosin

An efficient dispersive liquid-liquid microextraction using tetraalkylammonium bromide coated silver nanoparticles (DLLME-AgNPs) prepared in chloroform has been successfully applied as electrostatic affinity probes to the microextraction and preconcentration of terazosin prior to spectrofluorimetry analysis. This technique is based on a ternary system of solvents, where appropriate amount of mi...

Chemical nucleases as probes for studying DNA-protein interactions.

Over the past fifteen years much research has been devoted to the mode(s) by which the linear DNA macromolecule communicates with cellular proteins in the course of genetic programming, thus determining the patterns of growth and development in living organisms. A plethora of proteins have been shown to interact non-covalently with DNA either as structural elements, exemplified by the histones ...

Developing Adaptive Differential Evolution as a New Evolutionary Algorithm, Application in Optimization of Chemical Processes

Small DNA circles as probes of DNA topology.

Small DNA circles can occur in Nature, for example as protein-constrained loops, and can be synthesized by a number of methods. Such small circles provide tractable systems for the study of the structure, thermodynamics and molecular dynamics of closed-circular DNA. In the present article, we review the occurrence and synthesis of small DNA circles, and examine their utility in studying the pro...
