Ambient air plasmas have been known to kill cancer cells. To enhance selectivity we have used antibody-conjugated nanoparticles. We achieved five times enhancement of melanoma cell death over the case of the plasma alone by using an air plasma with gold nanoparticles bound to anti-FAK antibodies. Our results show that this new interdisciplinary technique has enormous potential for use as a complement to conventional therapies.

We address rhe problem of releoperaiing a mobile robot using shared autonomy: an on-boardcontrollerperforms obstacle avoidance while the operator uses ihe manipulandwn of a haptic probe io designate rhe desired speed and rare of turn. Sensors on the robot are used ro measure obsracle range informiion. We describe a strategy to convert such range information into forces, which are re- jlecied io the operaior's hand, via rhe haptic probe. This hapric infomation provides feedback io the operator in addition to imgeryfmm afmni-facing camera mounted on the mobile robot Extensive experiments with a user popularion show that the added hapiic feedback sign$icanily improves operaror pe~ormance in several ways (reduced collisions, increased minimum distance benveen rhe mboi and obstacles) wiihour a significant increase in navigation time.
