Description générale

Gelrite, gellan gum, is recommended as a gelling agent for use in place of agar in microbiological assay and tissue culture media. Gellan gum is used in a wide variety of immobilization matrices. It forms a hard gel at low concentrations in the presence of an electrolyte. Gellan is a linear tetrasaccharide composed of D-glucose, L-rhamnose, and D-glucuronic acid in the ratio of 2:1:1, linked by β (1 → 4) glycosidic bond.

Poly(tetrafluoroethylene) (PTFE) is a unique polymer with highly desirable properties such as resistance to chemical degradation, biocompatibility, hydrophobicity, antistiction, and low friction coefficient. However, due to its high melt viscosity, it is not possible to three-dimensional (3D)-print PTFE structures using
