Is porogen limited to organic materials only?

Porogens are substances used to create pores in a material, typically during the fabrication of scaffolds in tissue engineering. They can facilitate the development of a porous structure that is crucial for nutrient flow and cell migration. While many porogens are organic materials, such as sugar or salt, porogens can also include inorganic materials.

The notion that porogens are limited to organic materials is inaccurate, as inorganic substances, such as certain salts, can also serve as effective porogens. In some cases, inorganic porogens are utilized because they can dissolve in solution to create pores during the scaffold fabrication process.

Therefore, the statement that porogens are only organic materials is not correct. Porogen can indeed encompass both organic and inorganic materials, making it essential to understand the diversity and utility of porogens in the development of effective tissue engineering scaffolds.
