. Designed with the infrequent or novice user in mind, Easy AFM® provides a single interface that presents the user with all of the inputs required to obtain high quality Tapping Mode® images on a majority of samples in air. Two of the hardest things for new users to become familiar with is the process of mounting cantilevers and the alignment

The atomic force microscope (AFM) offers extraordinarily high resolution in force measurement applications, routinely yielding useful data down to the thermal noise floor of the cantilever, typically about 10pN. This along with the ease with which it is applied to many biological systems has made it a popular tool for studying such things as the specific

Fluorescence microscopy has become an indispensable tool in cell biology because it allows specific proteins to be visualized. Atomic force microscopy (AFM) is also becoming extensively used in the life sciences, but its development has largely followed an independent path and is used for somewhat different, but often complementary, purposes. Both methods

The ability of atomic force microscopy (AFM) to create three-dimensional micrographs with nanometer resolution has made it an essential tool in applications ranging from semiconductor processing to biology. In addition to this topographical imaging, the AFM can also probe nanomechanical and other fundamental properties of sample surfaces, including

Normal 0 false false false MicrosoftInternetExplorer4 TappingModeTM imaging has proved to be the most versatile mode of atomic force microscopy (AFM) in ambient conditions where the presence of a fluid layer (condensed water vapor and other contaminants) severely limits the applicability of both, contact mode and non-contact techniques. Overcoming the

Scanning tunneling microscopy (STM) employs a biased sharp metal probe in close proximity to a surface. When the tip-sample separation is small, there is a finite probability that electrons will tunnel across this gap. As the tip is scanned across the sample the tunneling current is utilized as a feedback signal in order to maintain the tip-sample separation

Normal 0 false false false MicrosoftInternetExplorer4 Current antibacterial drugs might become ineffective in the near future due to a phenomenon called pharmacoresistance. This refers to the ability of microorganisms to withstand bacteriocidal (cell killing) or bacteriostatic (inhibition of growth) effects caused by antibiotics1. Bacteria are known

The combination of optical with scanning probe microscopy techniques has become a powerful tool for sensing biological events on nanoscale. This combination will significantly contribute to providing new insights to the fields of biosensors, pharmacology, drug discovery, cancer research or nanomedicine over the next few years. In addition to its high
