Gold Nanoparticle Properties: PEG Length vs. Molecular Weight
Important reference for determining the diameter increase of gold nanoparticles
The following .exe calculates the PEG length and overall gold nanoparticle + PEG diameter given a PEG Molecular Weight and gold nanoparticle diameter. The PEG length is calculated based on the PEO unit length of 0.28 nm in water [Oesterhelt F, Rief M, Gaub HE (1999) Single molecule force spectroscopy by AFM indicates helical structure of poly(ethylene-glycol) in water. New J Phys 1: 6.1–6.11].
