One Label, Five Microscopies
A new type of nanoparticle works as a label for five types of microscopy. Different microscopy methods usually require different types of probes, making the resulting images difficult to correlate. Chemistry professor Jie Zheng and graduate student Chen Zhou of the University of Texas, Dallas, reported that metal nanoparticles can be used as universal probes for five types of microscopy—bright field, dark field, fluorescence, Raman, and two-photon excitation. Zheng attributed the particles’ versatility to . . .
