PLGA is a biocompatible, biodegradable, and non-toxic synthetic polymer. Its therapeutic applications have been approved by the U.S. Food and Drug Administration (FDA) and Europe the European Medicines Agency (EMA). One advantage of PLGA copolymers is that their properties can be engineered to achieve desired characteristics. PLGA is a copolymer of polylactic acid (PLA) and polyglycolic acid (PGA). By altering the ratio of lactic and glycolic acids in PLGA, different physical and chemical proper

Ametrine is a rare silicate mineral belonging to the quartz group, characterized by the coexistence of purple (amethyst) and yellow (citrine) color zones within a single crystal. This bicolored structure forms due to iron ions undergoing different oxidation states during crystal growth. Natural ametrine is commercially found only at the Anahí Mine in Bolivia, the sole known and continuously operated source of ametrine since the 17th century.Mineralogical PropertiesChemical Composition and Crysta

Ceramics are materials that are inorganic and typically have a crystalline structure, processed at high temperatures, and are hard, brittle, and heat-resistant. They are generally electrically insulating. They are one of the four main material groups in materials science. Ceramics stand out due to their structural strength, thermal and wear resistance, and chemical stability. They are used in both high-temperature applications and traditional applications. In materials engineering, the mechanica

Raman spectroscopy is a spectroscopic method based on light scattering, used to determine the molecular structure, chemical composition, and physical properties of materials. This technique was discovered in 1928 by Indian physicist C. V. Raman and earned him the Nobel Prize in Physics in 1930. Raman scattering arises from energy changes in photons as they interact with molecules in the sample. It has been reported that the use of Raman spectroscopy in biological analyses has increased by 30 per
