To detect a chemical of interest, analytical chemists sometimes toss antibody-coated beads into a solution to scavenge for it. To analyze their captured chemicals, chemists have to herd the beads together using centrifugation or magnetic fields. Now researchers report a faster, simpler method to concentrate their samples that relies on beads that float in a bubble (J. Am. Chem. Soc., DOI: 10.1021/ja208463f).
