Self-excited coupled cantilevers for mass sensing in viscous measurement environments

Hiroshi Yabuno, Yasuhiro Seo, and Masaharu Kuroda

The eigenstate shift in two nearly identical and weakly coupled cantilevers provides a means to realize much higher-sensitivity mass detection compared with the eigenfrequency shift approach. We propose using self-excited oscillations for eigenstate detection without using frequency response or re ... [Appl. Phys. Lett. 103, 063104 (2013)] published Wed Aug 07, 2013.

Enhanced biocompatibility for plasmid DNA on patterned TiO2 surfaces

Subrata Majumder, I. Mishra, and U. Subudhi et al.

An enhanced biocompatibility from nanodot patterned TiO2 surfaces, fabricated by ion beam sputtering, has been observed here through its interaction with plasmid DNA. Investigations of the persistence length and the areal conformation of DNA show that the biocompatibility increases with ion fluenc ... [Appl. Phys. Lett. 103, 063103 (2013)] published Wed Aug 07, 2013.
