General description

Goldnanoparticles with size of 5 nm and polydispersity index of <0.2 offer unique characteristics and have diverse applications in various industries. PBS maintains a physiological pH and prevents aggregation of nanoparticles. Smaller nanoparticles exhibit unique optical properties, including a strong surface plasmon resonance (SPR), which can be utilized in imaging and sensing applications. Small size also allows for enhanced permeability and retention effect in tumors, making them effective carriers for targeted drug delivery.
