Studies of bio-molecular dynamics in aqueous solutions using 147Nd nuclear probe — •Sardool Singh Ghumman — Department of Physics, Sant Longowal Institute of Engineering & Technology, Deemed University, Longowal 148 106 Punjab, India

Conventional perturbed angular correlation technique is employed to investigate molecular dynamics in aqueous solutions of biomolecules of TES (Ntris[ hydroxymethyl]methyl 2-Amino ethane sulphonic acid), BSA (Bovine Serum Albumin), Oxine (1,4-Benzodioxane-6-boronic acid pinacol ester) and EDTA (ethylenediaminetetraacetic acid) using 147Nd nuclear probe. In addition to the use of 147Nd radioactive probe that it proves to be helpful tool for perturbed angular correlation studies it also emerges out to understand the dynamics of molecules of bio-molecular compounds in aqueous environments. Considerable decrease in attenuation coefficient with higher molar concentrations is noticed for EDTA complexes while the attenuation effect has been found to be more pronounced for macromolecules of BSA and chelates of Oxine. Applications of this isotope are outlined for future non-bio-molecular materials too.
