In 1988, intrinsic localized mode (ILM) was theoretically discovered as a temporary periodic and spatially localized solution in a nonlinear coupled oscillator. This discovery triggered wide-spread investigations on energy localization phenomena in spatially discrete systems. In particular, observations of the ILM in micro-mechanical cantilever arrays enable us to expect that energy localizatio...

Current progress on the use of dynamic-mode cantilever sensors for biosensing applications is critically reviewed. We summarize their use in biosensing applications to date with focus given to: cantilever size (milli-, micro-, and nano-cantilevers), their geometry, and material used in fabrication. The review also addresses techniques investigated for both exciting and measuring cantilever reso...

This paper presents a review of micro- and nano-structure based oligonucleotide detection and quantification techniques. The characteristics of such devices make them very attractive for Point-of-Care or On-Site-Testing biosensing applications. Their small scale means that they can be robust and portable, their compatibility with modern CMOS electronics means that they can easily be incorporate...

Abstract: In recent years, MEMS/NEMS (Micro-/Nano Electro Mechanical Systems) sensors have attracted tremendous interest among researchers due to their low cost, quick response time, as well as high sensitivity and selectivity. In this paper, an ultra sensitive acetone sensor based on carbon nanotube (CNT) structure is proposed. In this device, a carbon nanotube is anchored to a substrate in on...

Plasmonic lithography with a contact probe records nano-meter scale features and has high-throughput owing to its capability to scan in contact mode. The probe is commonly based on a micrometer-scale cantilever, which leads to the tip-positioning problem due to force-deflection that induces lateral tip displacement. We propose a geometrically modified probe to achieve high positioning accuracy....

The cantilever sensor, which acts as a transducer of reactions between model bacterial cell wall matrix immobilized on its surface and antibiotic drugs in solution, has shown considerable potential in biochemical sensing applications with unprecedented sensitivity and specificity. The drug-target interactions generate surface stress, causing the cantilever to bend, and the signal can be analyze...

Cantilever vibration in fluid environment is probably one of the most common Fluid Structure Interaction (FSI) problems in the field of Micro/Nano Electro Mechanical Systems (MEMS/NEMS). Usually the effect of fluid on cantilever oscillation is characterized in terms of mode resonance frequencies and quality factors (Qs), being those two physical quantities what is actually measured in the dynam...

Micro-cantilevers are frequently used as scanning probes and sensors in micro-electromechanical systems (MEMS). Usually micro-cantilever based sensors operate by detecting changes in cantilever vibration modes (e.g., bending or torsional vibration frequency) or surface stresses when a target analyte is adsorbed on the surface. The catalyst for chemical reactions (i.e., for a specific analyte) c...

Since its introduction in 1986 as a tool for imaging and creating three-dimensional micrographs with resolution down to the nanometer and angstrom scales, the scanning probe microscope (SPM) has increasingly been acclaimed as a quantitative probe of surface forces such as adhesion. The SPM is able to study these important parameters using a technique that measures forces on the probe as it appr...
