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

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 "

In skeletal muscle the activation of phosphorylase b is catalyzed by phosphorylase kinase. Both enzymes occur in vivo as part of a multienzyme complex. The two enzymes have been imaged by atomic force microscopy and the results compared to those prev

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

The adaptation of a Digital Instruments DimensionTM 3000 atomic-force microscope to provide a near-field scanning optical microscopy capability is described. The enabling technology for the adaptation is the bent optical fiber probe. The design and o

This paper deals with the effect of C, Co, and Cr additions on the surface profile of Fe78 B13Si9 metallic glass at a nanoscopic scale. The seperate addition of the elements was successful in a way that three new metallic films with better properties

The muscle glycogenolytic complex is responsible for providing access to the reserve carbohydrate energy stores in skeletal muscle during times of vigorous exercise. The complex is a set of enzymes and regulatory factors that are bound to the carbohy

Enzymes can be immobilized at a solid–liquid interface and observed with a scanning tunneling microscope (STM) using the inherent charge of proteins and an external potential applied to the STM substrate. Phosphorylase kinase, and dimers and oligom

We have measured inelastic Compton scattering of 21-GeV bremsstrahlung photons on protons, for ${p}_{T}$ above 1 GeV/c. The yield of photons after subtracting ${\ensuremath{\pi}}^{0}$ and $\ensuremath{\eta}$ decay contributions appears to be nonhadro
