摘要：

We have developed a novel, operator-friendly, nanothermite reaction actuator which generates transient pressures comprised of a shock wave superimposed on a broad pressure pulse to facilitate intranuclear molecular transport. The actuator demonstrates the delivery of similar to 70 kDa FITC-Dextran into chicken cardiomyocytes with cytoplasmic delivery efficiency greater than 90%, maximum intranuclear delivery efficiency of 84%, and cell survival rates exceeding 95% in minimum operating pressure conditions. Tunable nanothermite reactions enable versatile pressure generating characteristics which can extend the technology to a spectrum of biomedical molecular delivery applications. (C) 2012 Elsevier B.V.
