Aminopropyl-functionalized Mesoporous Silica nanoparticle surface (APMS)

Aminopropyl-functionalized Mesoporous Silica (APMS) nanoparticle surfaces are engineered materials used primarily as scaffolds for drug delivery and diagnostic imaging (Vallet-Regí et al., 2007). These nanoparticles feature a high surface area and a porous structure, with the surface modified by aminopropyl groups to facilitate the attachment of therapeutic agents, targeting ligands, or fluorescent markers (Slowing et al., 2008). While APMS nanoparticles are not biological targets themselves, they are critical components in nanomedicine for improving the solubility, stability, and site-specific delivery of drugs. Their role in disease treatment is indirect, serving as vehicles to transport active pharmaceutical ingredients to specific tissues, such as tumors, while minimizing systemic toxicity (Argyo et al., 2013). Research focuses on optimizing their surface chemistry to enhance biocompatibility and control the kinetics of drug release. The amino groups on the surface allow for pH-responsive release mechanisms, which is particularly useful in the acidic microenvironment of cancer cells. Furthermore, these surfaces can be functionalized with polyethylene glycol (PEG) to increase blood circulation time and evade the immune system (Manzano & Vallet-Regí, 2020).
