Polymorph Control of Sulfathiazole in Supercritical CO2

Pharmaceutical Research, 2001
Sulfathiazole was used to investigate polymorph control in liquid and supercritical CO2. Conventional techniques require a variety of solvents and techniques to produce different polymorphs. The present approach involves precipitation from an organic solution with liquid or supercritical CO2 using the SEDS process.Sulfathiazole was precipitated from ...

Supercritical CO2-assisted decellularization

Introduction: Decellularization is a procedure that aims to remove the cellular and antigenic material of a tissue while preserving its extracellular matrix (ECM) and biological properties. Decellularized ECM offers a natural microenvironment with significant potential for use in cell-based therapies and tissue regeneration [1].
