Collagen and Its Derivatives Serving Biomedical Purposes: A Review.

Biomaterials have been the subject of extensive research, and their applications in medicine and pharmacy are expanding rapidly. Collagen and its derivatives stand out as valuable biomaterials due to their high biocompatibility, biodegradability, and lack of toxicity and immunogenicity. This review comprehensively examines collagen from various sources, its extraction and processing methods, and its structural and functional properties.

Application of micro-solid-phase extraction for determination of released dental fillings components in artificial saliva solution.

In this work, the microextraction devices in form of sachets were prepared and used for isolation of released dental fillings components from artificial saliva solutions As sorbents mesoporous aluminosilicate and C18-bonded silica were used. Gas chromatography was used for indication of analytes in samples. The dependence of adsorption on variable factors were determined.
