摘要: We report a simple and highly versatile system to select weigh individual dry biological particles. The is composed of microtweezer pick place particles cantilever-based resonator them. can entities that vary from red blood cell (~10−11 g) the eye–brain complex an insect (~10−6 g), covering 5-order-of-magnitude mass range. Due its versatility ease use, this weighing method compatible with established laboratory practices. provide complementary information for wide variety imaged using scanning electron microscopy determine comparative weights are attached microparticles as well fractions have been subjected focused ion beam milling.
