Comprehensive investigations of geological samples can be challenging due to variations in size, shape, structure and composition. For that reason flexible analysis techniques are required which can be easily adapted to individual sample characteristics.

New blueDrive Photothermal Excitation for Asylum Research Cypher AFMs uses a modulated blue laser to directly drive the cantilever during AC mode imaging, producing an ideal frequency and phase response.
AC modes typically rely on piezoacoustic drive, which in liquid produces an obviously distorted and time-varying response. In air, the high Q of the lever can mask the problem, but it still interferes with quantitative analysis.

Researchers at the Georgia Institute of Technology have "painted" the world's most famous painting Mona Lisa on a substrate surface approximately 30 microns in width - or one-third the width of a human hair. The team's creation, the "Mini Lisa," demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices because the team was able to vary the surface concentration of molecules on such short-length scales.

Following traumatic injury, skin has the capacity to repair itself through complex biochemical changes. The dermis is remodeled over time affecting its mechanical behavior. AFM nanoindentation showed that the scar tissue exhibits stiffer behavior than healthy skin. Scar tissue shows weaker visco-elastic creep and reduced capability to dissipate energy at physiological frequencies than adjacent intact skin. AFM imaging showed a distinct orientation of collagenous fibrils in the scar tissue.

A high-power atomic force microscope that could revolutionize the study of materials at high temperatures and pressures is coming into focus in a Wright State University lab. Steven Higgins and his team are building a new version of the hydrothermal atomic force microscope, an instrument that could unlock scientific mysteries and be used in the study of oil production, hydrofracturing of rock layers, storage of radioactive waste and the capture and storage of atmospheric carbon dioxide.

Researchers have married two biological imaging technologies, creating a new way to learn how good cells go bad. "Let's say you have a large population of cells," said Corey Neu, an assistant professor in Purdue University's Weldon School of Biomedical Engineering. "Just one of them might metastasize or proliferate, forming a cancerous tumor. We need to understand what it is that gives rise to that one bad cell."

Carbon nanotubes (CNT) have been demonstrated since 1996 as ideal probes for scanning probe methods because of their nano-size, their cylinder geometry and their mechanical properties. Their use hasn‘t spread out as expected, due to lack of control of their fabrication and of their interaction with surfaces. Sixteen years later, this knowledge is now acquired. Carbon nanotube probes can provide more than high resolution thanks to their high mechanical and chemical stability and surface sensitivity.
