A simple and green process to prepare copper iodide in nano scale via sonication was carried out. Subsequently, this nanoparticles was used as an efficient catalyst for the synthesis of 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones via four-component reaction of hydrazine, ethyl acetoacetate, aldehyd

Phosphorylation of DNA by polynucleotide kinase (PNK) takes an important role in DNA damage repair, replication and recombination. The evaluation of PNK activity has received an increasing attention due to the significance of PNK. Here, we present a label-free fluorescent method for PNK activity ass
