Molecular robots latch onto cells, ID them for drugs
The molecular bots were used in experiments with lymphocytes, a type of white blood cell.(Credit:Wikimedia Commons)Sometimes I can't believe that it's 2013 and we still don't have tiny, disease-fighting robots swimming around in our bodies. Well, researchers at the Hospital for Special Surgery in New York and Columbia University haven't created exactly that, but they have produced little critters that can latch onto targeted cells and "label" them. The so-called molecular robots (aka molecular automata) are made up of antibodies and short snippets of DNA. In a study in Nature Nanotechnology, the researchers described how these molecular robots could help design drugs that target harmful cells and leave surrounding beneficial cells guild wars 2 Power leveling alone.

Receptors are like keyholes on cell surfaces that interface with external molecules to trigger cell functions or behavior. The automata in the study were designed to target lymphocytes, a type of white blood cell, in blood samples taken from healthy people. Once the automata http://www.rmtbuddy.com/guild-wars-2-gold-us-powerleveling.html targeted the cells, they fused and formed new strands of DNA. The researchers were able to get the newly created strands to fluoresce in a solution, which would allow for populations of target cells to be labeled for identification and specific therapies. "This is a 'proof of concept' study using human cells," study coauthor Sergei Rudchenko said in a release. "The next step is to conduct tests in a mouse model of leukemia." If animal and human trials work, such molecular robots could be used to design drugs that fight cancer and autoimmune disorders without damaging healthy cells. Because I can't break my addiction to calorie-rich bowls of ramen noodles, I'll be waiting for molecular bots that can clean out my arteries. Come on, science! Chop chop!
