1. INTRODUCTION The miniaturization of structures in the guise of nanoscale materials has created a so-called nanoplatform for applied biomedical research in developing novel and improved diagnos-tics and therapeutics. 1 Nanoparticles offer large surfaces for reactions involving biomolecules, thus providing a promising pathway to combine biomolecular(More)
First principles density functional theory calculations are performed on tryptophan-ZnO nanoparticles complex in order to study site specific interactions between tryptophan and ZnO. The calculated results find the salt bridge structure involving the -COOH group and ZnO cluster to be energetically more favorable than other interacting sites, such as indole(More)
We present the results of first-principles molecular orbital calculations describing the interaction of metallic nanoparticles, represented by Mn(13), Ag(13), and Al(13) atomic clusters, with a biologically active molecule, dopamine. The interaction strength, determined in terms of the nanoparticle-molecule complex binding energy, is found to be higher for(More)
