25 years of scanning probe microscopy and no standards yet

It has been 25 years since the scanning tunneling microscope (STM) was invented, followed four years later by the atomic force microscope, and that's when nanoscience and nanotechnology really started to take off. Various forms of scanning probe microscopes based on these discoveries are essential for many areas of today's research. Scanning probe techniques have become the workhorse of nanoscience and nanotechnology research. Given the 25-year development timeframe, it is surprising that even today there is no generally accepted standard for scanning probe microscopy (SPM). There is no unified SPM terminology, nor is there a standard for data management and treatment, making access and processing of SPM data collected by different types of instruments an error-prone exercise. SPM standardization has only recently begun as part of an effort by the International Organization for Standardization (ISO) the largest developer of industrial standards. Meanwhile the development of SPM instruments and analysis software continues, increasing the already large family of scanning probe microscopy.
