Lab on a Watch (IMAGE)
Caption
Surface-functionalized superparamagnetic particles emulsified in mineral oil turn a free-standing droplet into a flexible virtual laboratory with (sub)microliter volumes. By using magnetic forces, rare acute monocytic leukaemia cells are extracted from blood, preconcentrated, purified, lysed and subjected to a real-time PCR in minutes. The PCR works like a clockwork by rotating the droplet over different temperature zones.
