Friction forces between a sharp silicon nitride tip (radius of curvature, 10 nm) and mica were measured using a friction force microscope. Under low load conditions (

In this study we investigated the applicability of the (silver- enhanced) immunogold labeling method for atomic force microscopy. Human lymphocytes were labeled with anti-CD3 conjugated to fluorescein isothiocyanate and a secondary antibody (goat ant

A flow cytometer using a solid state light source and detector was designed and built. For illumination of the sample stream two types of diode lasers (670 nm and 780 nm) were tested in a set-up designed to differentiate human leukocytes by means of

The chromosomal structure which is specific for meiosis, the synaptonemal complex (SC), plays a major role in chromosome pairing and the recombination of genetic material. The SC was studied using atomic force microscopy (AFM). The results of this st

Atomic force microscopy (AFM) permits one to generate a topographic representation of the sample under investigation with high spatial resolution. We assumed that cytochemical staining techniques, which yield reaction products which can be discrimi

The feasibility of using immunogold labels as cell-surface markers in atomic force microscopy is shown in this paper. The atomic force microscope (AFM) was used to image the surface of immunogold-labeled human lymphocytes. The lymphocytes were isolat

SUMMARY An atomic force microscope (AFM) was combined with a conventional optical microscope. The optical microscope proved to be very convenient for locating objects of interest. In addition, the high-resolution AFM image can be compared directly wi

The atomic force microscope (AFM) is used to image the surface of both conductors and nonconductors. Biological specimens constitute a large group of nonconductors. A disadvantage of most AFM's is the fact that relatively large areas of the sample su

A shot-noise- and diffraction-limited Michelson interferometer and two optical beam deflection configurations are compared for application in an atomic force microscope. The results show that under optimal conditions the optical beam deflection metho

Friction measurements on muscovite mica and glass have been performed with a friction force microscope using Si3N4 tips. The environment was changed from ambient conditions to N2‐ or Ar‐gas conditions. In ambient conditions, the friction‐versus
