SpecNano™ Carboxyl, PEG3000, Gold Nanostars, 100 nm(CGSC-3K--100)


50 OD carboxyl gold nanostars, 100 nm diameter, absorbance max 680 nm, are monodispersed gold nanostars fuctionalized with carboxyl groups and have a narrow size distribution (<10%). There is a PEG (3 kDa) spacer-SH between the gold surface and carboxyl-groups. These carboxyl gold nanostars are ideal for conjugation of proteins using standard EDC/NHS coupling chemistry.
