Gold Nanoparticles – Methoxy PEG
Price range: €186.00 through €894.00
Methoxy PEG gold nanoparticles for in vivo imaging and drug delivery applications, with reduced protein binding and excellent colloidal stability.
Description
PEG Gold Nanoparticles are functionalized with methoxy-terminated polyethylene glycol (PEG), offering a non-reactive and hydrophilic surface. The methoxy group prevents further conjugation, making these particles ideal for minimizing nonspecific interactions in biological systems.
Applications:
- In vivo imaging and biodistribution studies
- Development of long-circulating therapeutic nanoparticles
- Reducing background in diagnostic assays
These nanoparticles are monodisperse, optically tunable, and highly stable in complex media.
Nanoparticle Diameter Options: 4 nm, 7 nm, 15 nm, 30 nm, 45 nm, 60 nm, 80 nm, 100 nm, 150 nm, 200 nm
PEG Spacer Options: 1 kDa, 2 kDa, 5 kDa, 10 kDa
Volume (@ 50 OD): 0.4 mL, 1 mL, 3 mL
