摘要： Apparatus and methods for identifying the nature of an unidentified substrate present in trace amounts of known gaseous or liquid media such as air or water include collecting a sample of the substance in the media, filtering and concentrating the sample, depositing at least a portion of the sample on a known substrate, analyzing the deposited sample utilizing SETM, NFOM and/or AFM techniques to form one or more images characteristic of the unidentified substance, and then identifying the substance by comparing the images so obtained to images of known substances obtained using the same techniques.
