Report

Fast, High Resolution and Wide Modulus Range Nanomechanical Mapping with Bimodal Tapping Mode

Autor: Kocun, Marta, Labuda, Aleksander, Meinhold, Waiman, Revenko, Irene, Proksch, Roger

Tapping mode atomic force microscopy (AFM), also known as amplitude modulated (AM) or AC mode, is a proven, reliable and gentle imaging mode with widespread applications. Over the several decades that tapping mode has been in use, quantification of t

Report

Calibration of higher eigenmodes of cantilevers

Autor: Labuda, Aleksander, Kocun, Marta, Walsh, Tim, Meinhold, Jieh, Proksch, Tania, Meinhold, Waiman, Lysy, Martin, Proksch, Roger

A method is presented for calibrating the higher eigenmodes (resonance modes) of atomic force microscopy cantilevers that can be performed prior to any tip-sample interaction. The method leverages recent efforts in accurately calibrating the first ei

Single molecule force measurements of chitosan

Autor: Kocun, Marta

Chitosan, a glucosamine polysaccharide derived form chitin, was studied by AFM-based single molecule force spectroscopy. The goal of this study was to investigate chitosan's adhesive properties to various surfaces ( i.e. mica, glass, quartz, polytetr

Photothermally Excited Contact Resonance Imaging in Air and Water

Autor: Kocun, Marta, Labuda, Aleksander, Gannepalli, Anil, Proksch, Roger

Contact Resonance Force Microscopy (CR-FM) is a leading AFM technique for measuring viscoelastic nano-mechanical properties. Conventional piezo-excited CR-FM measurements have been limited to imaging in air, since the "forest of peaks" frequency resp
