Lab in a Drop
They have now developed a rapid test for genetic diagnosis that combines the preparation of biological samples with a polymerase chain reaction (PCR) on one chip. As they report in the journal
Angewandte Chemie
, the “laboratory device” for all steps in this system is a single drop containing magnetic nanoparticles, which is moved across the chip by a magnetic field.
PCR allows gene sequences to be duplicated and identified—to identify a disease trigger, for example. In this process, the sample must cycle through a specific sequence of temperatures. Because of the slow heating and cooling processes, laboratory PCR usually takes several hours. The new chip PCR requires only minutes, including for the sample preparation.
In contrast to other chip-based methods, the actual sample, such as a drop of blood, can be placed directly on the PCR chip, where it is mixed with a drop that contains magnetic particles. These particles are equipped with antibodies on their surface, antibodies that bind specifically to the interesting cells in the blood.
