Perfecting a viral pack mule

Viruses aren't always bad. In fact, scientists can harness the capabilities of some viruses for good—modifying the viruses to carry drug molecules, for example.

Chemists weigh intact virus mixture with mass spectrometer

Carnegie Mellon University chemists, led by Mark Bier, have separated and weighed virus particles using mass spectrometry (MS). This is the first time that researchers successfully used matrix-assisted laser desorption ionization ...
