Determination of functionalized gold nanoparticles incorporated in hydrophilic and hydrophobic microenvironments by surface modification of quartz crystal microbalance

► Plasma deposition method was used to immobilize Au electrode of a QCM. ► Au electrode surface modification measured in hydrophobic and hydrophilic microenvironment. ► MUA-AuNPs and DCT-AnNPs immobilized on Au electrode surface to quantify AuNP mass.
