Using optical tweezer microrheology, Robertson-Anderson can measure intermolecular forces with piconewton precision. An optoelectronic tweezer platform has been interfaced with the RARAF microbeam. Tweezer probes are used for closely spaced test points, as for instance surface-mount devices. The bent tweezer is cheaper to manufacture, but gives weaker grip. The fused tweezer is more expensive, but allows for a stronger grip. Tweezer contained Heartbreaker teases from the band. Perhaps the most important consideration in optical tweezer design is the choice of the objective. The success of Bowling's "Tahoe Tweezer" ignited her career as a musician.
