Ultra-thin liquid control plate and combination of box-like member and the control plate for electron microscopy

摘要

An ultra-thin liquid control plate (10) and a combination of a box-like member and the control plate include a plate-like member (11) having at least one view hole (12). The joint surface combined with a sidewall of the view hole and a surface of the plate-like member is provided with at least one more-hydrophilic section (123) and at least one less-hydrophilic section (121), wherein the more-hydrophilic section has a height smaller than 50µm. While combined with the box-like member, the plate-like member is mounted in the box-like member. The box-like member has at least one through hole running through each of a top side and a bottom side thereof and coaxially aligned with the view hole. After a liquid is placed into the view hole, the more-hydrophilic section adsorbs the liquid to form a liquid layer and the less-hydrophilic section is hydrophobic to adsorb no liquid.
