Small molecule imaging future

STM and AFM methods can be used as a nanoscale quantitative analysis tool for materials on surfaces (e.g., pollution control). This was mentioned earlier where 60 x 10 cholesterol molecules were estimated in the image. The lower limit in detection by AFM or STM is theoretically one atom or molecule (i.e., 10 mol ). This means that quantitative analysis has an extreme lower limit for detection, which is important in pollution control, etc. where very small amounts must be monitored. On this subject of the nanoanalytical application of both STM and AFM much remains to be smdied. It is obvious that in the future of nanochemistry will develop based on such nanosystem studies. The nanocrystal smdies of amino acids as described above are also another area that will develop based on these procedures.
