Biomedical Applications of Aerogel

Aerogels have garnered significant attention in biomedical applications due to their unique properties. This review explores three key areas: biosensing, imaging, and bone regeneration. In biosensing, aerogels serve as excellent platforms for immobilizing biomolecules, enabling sensitive detection of analytes through various mechanisms such as fluorescence or surface plasmon resonance. In imaging, their low density and high surface area make aerogels promising candidates for contrast agents and drug delivery vehicles in magnetic resonance imaging and computed tomography. Furthermore, their biocompatibility and tunable porosity render aerogels suitable scaffolds for bone regeneration, promoting cell adhesion, proliferation, and mineralization. This abstract underscores the multifaceted roles aerogels play in addressing diverse biomedical challenges, paving the way for future breakthroughs in healthcare.
