A galinstan expansion femtosyringe enables femtoliter to attoliter samples to be introduced into prokaryotes and subcellular compartments of eukaryotes. The method uses heat-induced expansion of galinstan (a liquid metal alloy of gallium, indium, and tin) within a glass syringe to expel samples through a tip diameter of about 0.1 μm. The narrow tip inflicts less damage than conventional capillaries, and the heat-induced expansion of the galinstan allows fine control over the rate of injection… CONTINUE READING
