New, more sensitive sensor for evaluating drug safety

A new technique for evaluating drug safety can detect stress on cells at earlier stages than conventional methods, which mostly rely on detecting cell death. The new method uses a fluorescent sensor that is turned on in a ...

Tumble-proof cargo transporter in biological cells

ver wondered how a molecular nanomotor works when repairing DNA or transporting material such as organelles in the cell? Typically, nanomotors move along biopolymer filaments to go about their duties in the cell.  To do ...

Rice scientists synthesize anti-cancer agent

A team led by Rice University synthetic organic chemist K.C. Nicolaou has developed a new process for the synthesis of a series of potent anti-cancer agents originally found in bacteria.

Pairing pain medicine with metal ions to battle cancer

Fighting chemoresistant cancer remains a huge challenge that scientists are tackling from as many angles as they can. One alternative approach involves pairing two groups of compounds—pain medicine and metal ions—that ...

DNA 'building blocks' pave the way for improved drug delivery

DNA has been used as a 'molecular building block' to construct synthetic bio-inspired pores which will improve the way drugs are delivered and help advance the field of synthetic biology, according to scientists from UCL ...
