Nanoparticles generally refer to particles in the size range of 0.1 to 100 nm, where particles show completely novel physicochemical properties from their bulk counterpart. The promise of nanoparticles for diagnostic and therapeutic applications has been widely explored. For diagnostic applications, the specificity and sensitivity of imaging can be greatly improved by using nanoparticles as contrast enhancement agents. As therapeutic agent, nanoparticles enable targeted and controlled drug delivery.

Compared to spherical nanoparticles, unique optical properties appear. For example, gold particles with spikes give high signal in surface-enhanced Raman spectroscopy (SERS) due to enhancement of the electromagnetic field on the surface. Creative Diagnostics provides NanoCubes, NanoStars, NanoBipyramids, NanoClusters, NanoHollows, NanoCages, NanoShuttles, NanoPlates and NanoChains for various applications, with unique optical properties.

Take NanoCages as an example. They can have strong absorption (for the photothermal effect) in the near-infrared while maintaining a compact size. Nanocages are well suited for in vivo studies owing to the high transparency of soft tissue in the near-infrared region. Creative Diagnostics' standard gold NanoCages are citrate stabilized. Other ligands, such as Aromatic hydrocarbons, Carboxyl, Amine can also be provided as requested. With years of experience in the pharmaceutical and life science sector, Creative Diagnostics recently launches a wide range of Special Shape Particles for researchers.
