NanoStars

We provide Nanostars functionalized with active groups such as NHS, carboxyl, amine and hydroxyl.Gold nanostars have unique optical properties compared to spherical gold nanoparticles of the same core diameter. The spiky uneven surface causes a red shift in the surface plasmon peak and a larger enhancement of the electromagnetic field at the tips of the gold nanostars spikes compared to that of spherical particles

Diameter: 50nm,60nm,70nm,80nm,90nm,100 nm

Absorption Max: 585-680 nm
