Tris-HCl is one of the components of TE buffer solution, which is used to keep the pH at nearly constant value for storing DNA and RNA[1]. With the help of the pH balancing feature of tris, it is commonly used asa molecule in the buffer solutions. Tris has globular shape and has orientationally disordered crystal structure. Tris crystallizes in the orthorhombic system and in a layered structure with weak hydrogen bonds in each layer[2]. Tris is used in medicine and solar cell systems as an organic thermal energy storage material [3]. Tris can be observed in far-infrared region of high pressure Raman spectroscopy[4,5]. Although there are some investigations on crystallization property and molecular structure of tris, the investigations of tris on solid surfaces were inadequate[6].

Tris-HCl

In our laboratory, we are working on the relation of Tris-HCl and different surfaces and investigation of different coating parameters and coating techniques.
