1. Modeling the pull-in instability of the CNT-based probe/actuator under the Coulomb force and the van der Waals attraction
Carbon nano-tube (CNT) is applied to fabricate nano-probes, nano-switches, nano-sensors and nano- actuators. In this paper, a continuum model is employed to obtain the nonlinear constitutive equation and pull-in instability of CNT-based probe/actuators, which includes the effect of electrostatic interaction and intermolecular van der Waals (vdW) forces.

2. Processing and functionalization of tips for biologial applications of atomic force microscopy / Processamento e funcionalização de pontas para aplicações biologicas de microscopia de força atomica
Este trabalho teve como objetivo implementar a técnica de espectroscopia de força no Microscópio de Força Atômica (AFM) existente no LPD/IFGW/UNICAMP e aplicá-la ao estudo de pontas e amostras funcionalizadas com tiol (mercaptoundecanoic acid). Em particular, foi necessária uma caracterização minuciosa da ponta de AFM, utilizando imagens de microsco

3. Carbon nanotube atomic force microscopy tips: Direct growth by chemical vapor deposition and application to high-resolution imaging
Carbon nanotubes are potentially ideal atomic force microscopy probes because they can have diameters as small as one nanometer, have robust mechanical properties, and can be specifically functionalized with chemical and biological probes at the tip ends. This communication describes methods for the direct growth of carbon nanotube tips by chemical vapor dep
