Qcm-d study of nanoparticle interactions
WebAll flows through the QCM-D were kept at the rate of 0.15 mL/min. After establishing this baseline in ultrapure water, gold NPs in water (7.14 × 1010particles/mL) were allowed to flow for 10 min. NP–mem- brane interactions occur rapidly followed by steady-state frequency and dissipation changes. WebMinimum sample volume, stagnant mode. ~ 40 μl. ~ 10 μl using add-on module (QSense Open module) Minimum sample volume, flow mode. ~ 200 μl. Flow rates. 25-150 μl/min applicable for QSense setup (Peristaltic pump settable to 0-1 ml/min) Maximum time resolution*. 300 datapoints per second (each datapoint represents an f and D value)

WebDec 5, 2016 · The interaction of NPs with SLBs is highly influenced by the quality of the lipid bilayers. Unlike many surface sensitive techniques, by using QCM-D, the quality of SLBs can be assessed in real-time, hence QCM-D studies on SLB-NP interactions are less prone to the artifacts arising from bilayers that are not well formed.
