Washington: A new technique using molecular robots could help develop more targeted drugs, a new study has revealed.Sergei Rudchenko, Ph.D., director of flow cytometry at Hospital for Special Surgery (HSS) in New York City and a senior author of the study, said that the next step is to conduct tests in a mouse model of leukemia.In the new study, which is a collaboration between researchers from HSS and Columbia University, scientists designed molecular robots that are capable of identifying multiple receptors on cell surfaces, thereby effectively labeling more specific subpopulations of cells. The molecular robots, known as molecular automata, are composed of a mixture of antibodies and short strands of DNA. These short DNA strands, otherwise called oligonucleotides, can be manufactured by researchers in a laboratory with any user-specified sequence.
