Modelling and biomedical applications of ultrasound contrast agent(UCA) microbubbles have attracted a great deal of attention. In this review, we summarize a series of researches done in our group, including(i) the development of an all-in-one solution of characterizing coated bubble parameters based on the light scattering technique and flow cytometry;(ii) a novel bubble dynamic model that takes into consideration both nonlinear shell elasticity and viscosity to eliminate the dependences of bubble shell parameters on bubble size;(iii) the evaluation of UCA inertial cavitation threshold and its relationship with shell parameters; and(iv) the investigations of transfection efficiency and the reduction of cytotoxicity in gene delivery facilitated by UCAs excited by ultrasound exposures.
