According to FCNT probe manufacture technology, it adopts Micro Electronic Mechanical system (MEMS) [1] (refer to Figure 1) and electrophoresis technology [2] [3] (refer to Figure 2) to let CNT attach to the front edge of cantilever beam and in the front of the tip (refer to Figure 3). In doing this, we can use the FCNT to approach the sample quickly and reduce the testing time because the func...

Dip-pen nanolithography (DPN) uses scanning probes to directly deposit chemical and biological materials on a solid substrate. It offers the advantages of nanometer resolution and flexibility in pattern generation. Conventional DPN uses a single probe and its throughput is limited due to the serial nature of the process. This article reports the development of a linear silicon probe array that ...

Micro-cantilever sensors are widely used to detect biomolecules, chemical gases, and ionic species. However, the theoretical descriptions and predictive modeling of these devices are not well developed, and lag behind advances in fabrication and applications. In this paper, we present a novel multiscale simulation framework for nanomechanical sensors. This framework, combining density functiona...

Scanning tunneling microscopes (STMs) and atomic force microscopes (AFMs), known under the expression scanning probe microscope (SPM), are well established methods to analyze surfaces, and the principle of their operation is published widely [1-3]. In AFM a point probe reacts mechanically on interatomic forces of the sample and generates a topographic view of the surface with an atomic resoluti...

Recent experiments show that the adsorption of biomolecules on one surface of a microcantilever generates surface stresses that cause the cantilever to deflect. If a second species binds to the adsorbed molecules, the stresses change, resulting in a different deflection. By choosing adsorbed probe molecules that recognize specific molecules, it may be possible to detect pathogens and biohazards...

The closed-form solution of the transient response of damped dynamic force microscopy subjected to the nonlinear interatomic force is derived. The frequency shift and the decay rate of a V-typed probe can be determined easily and precisely by the proposed method. If the taper ratio is zero, a uniform cantilever is obtained. Moreover, the transient response of a non-uniform cantilever can be det...
