摘要：
A method based on the AFM and colloidal probe techniques was proposed to directly measure nonspecific interactions between QDs and different proteins with respective sizes and isoelectric points. Results indicated that van der Waals forces were the leading force, while electrostatic interactions also played an important role in nonspecific interactions.
