Patent number: 9312095Abstract: A method and system is provided for automatically preparing transmission electron microscopy (TEM) samples for examination by depositing extremely small samples onto a grid without need for a blotting step. A sample liquid droplet is formed at the end of a capillary, wherein a portion of the liquid is transferred to the TEM sample grid by contact. The excess volume in the liquid droplet is then retracted by an adjacent capillary. After a predetermined time interval, the retraction capillary is moved toward the drop of the sample to remove the excess volume. As compared to a conventional machine, where the blotting procedure can deform the structure of the molecule of interest, the present invention utilizes a very low shear rate for removal of the excess sample fluid.Type: GrantFiled: March 24, 2011Date of Patent: April 12, 2016Assignees: BROWN UNIVERSITY, RHODE ISLAND BOARD OF EDUCATION, STATE OF RHODE ISLAND AND PROVIDENCE PLANTATIONSInventors: Anubhav Tripathi, Jinkee Lee, Arjit Bose
