Two new methods for probing evanescent fields using a Dimension™ 3000 atomic force microscope (AFM) from Digital Instruments are described. The first method uses a fiber-optic pickup probe to collect light generated by a commercial silicon AFM prob

We have designed and tested a family of silicon nitride cantilevers ranging in length from 23 to 203 μm. For each, we measured the frequency spectrum of thermal motion in air and water. Spring constants derived from thermal motion data agreed fairly

A new optical‐lever based atomic force microscope is described in which the cantilever scans and is accurately tracked by a scanning focused spot. It can operate at forces below one nanoNewton over image areas greater than 100 μ×100 μ. It can be

Aerocapture, which has been described as "essential for cost-effective space transportation," imposes severe guidance and control problems. A closed-loop control law is formulated that provides stable control in the presence of reasonable errors in a

Three advances involving DNA in atomic force microscopy (AFM) are reported here. First a HEPES-Mg buffer has been used that improves the spreading of DNA and provides good DNA coverage with as little as 200-500 picograms per sample. Second, the new "

The effects of Pseudomonas putida ATH2-1RI/9 and Acidovorax delafieldii ATH2-2RS/1 on rhizosphere colonization, cyanide production, and growth of velvetleaf and corn was examined. When formulated in alginate beads and inoculated onto velvetleaf and c

We have applied a new generation of short cantilevers with high resonant frequencies to tapping mode atomic force microscopy of a process in situ. Crystal growth in the presence of protein has been imaged stably at 79 lines/s (1.6 s/image), using a 2
