Measuring the mass of molecules on the nano-scale

By observing the shift in eigenstates of coupled microcantilevers, researchers can measure nanogram-scale mass in a liquid environment with extreme accuracy

04-Jun-2015

Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error - potentially ...

'Parachuting' boron on benzene rings

A bulky catalyst induces pinpoint targeting on benzene to create bioactive molecules

16-Apr-2015

Tuning the para position of benzene moieties is significant for creating biologically active compounds and optoelectronic materials. Yet, attaching a functional handle specifically at the para position of benzene has been challenging due to multiple reactive sites on the ring. Chemists at ITbM, ...
