일반 설명
HEPES (4-(2-Hydroxyethyl)piperazine-1-ethanesulfonic acid) is a widely used Good’s buffer in biochemical and biological research applications. As a zwitterionic buffer, it stabilizes the pH of the solution even when small amounts of acid or base are added.
애플리케이션
HEPES potassium salt has been used as a buffering agent in nanopore fabrication and electrolyte preparations. It has also been used as a component of cell lysis buffer.

Thin membranes are highly sought-after for nanopore-based single-molecule sensing, and fabrication of such membranes becomes challenging in the ≲10 nm thickness regime where a plethora of useful molecule information can be acquired by nanopore sensing. In this work, we present
