Micromechanical cantilever-based biosensors
TL;DR: In this paper, the authors summarize how cantilever-based sensors can be operated, and their working principle is presented in few selected biosensing experiments which have been performed recently in our groups in the study of biotin-streptavidin and antigen-antibody interactions, and specific surface charge development of organic molecules.

Christoph Hagleitner,Andreas Hierlemann,Dirk Lange,Arthur Kummer,Nicole D. Kerness,Oliver Brand,H. Baltes +6 more
TL;DR: This work combines several of these developments to fabricate a smart single-chip chemical microsensor system that incorporates three different transducers (mass-sensitive, capacitive and calorimetric), all of which rely on sensitive polymeric layers to detect airborne volatile organic compounds.

Cavity cooling of a microlever
Constanze Metzger,Khaled Karrai +1 more
TL;DR: Direct experimental evidence for passive (or intrinsic) optical cooling of a micromechanical resonator is reported and cavity-induced photothermal pressure is exploited to quench the brownian vibrational fluctuations of a gold-coated silicon microlever from room temperature down to an effective temperature of 18 K.
Journal ArticleDOI
Scanning thermal microscopy
TL;DR: In this article, the authors present a review of the technology of scanning thermal microscopy and its applications in thermally probing micro-and nanostructured materials and devices and identify the parameters that control the temporal and temperature resolution in thermometry.

Atomic force microscope
TL;DR: The atomic force microscope as mentioned in this paper is a combination of the principles of the scanning tunneling microscope and the stylus profilometer, which was proposed as a method to measure forces as small as 10-18 N. As one application for this concept, they introduce a new type of microscope capable of investigating surfaces of insulators on an atomic scale.
