Background: We developed the CellTracks cell analysis system that, similar to flow cytometry, yields multiparameter information by which the cells can be differentiated. We describe the implementation of a laser scanning imaging method in the system.

Two-Color Fluorescence in Flow Cytometry DNA Sizing: Identification of Single-Molecule Fluorescent Probes

Autor: and Bart G. de Grooth, Jan Greve, Juleon M. Schins, A. Agronskaia

Publikováno v: Analytical Chemistry. 71:4684-4689

We have built a two laser flow cytometer for ultrasensitive fluorescence measurements. The instrument is used for two-parameter analysis of DNA fragments. Total DNA content of each fragment (proportional to its size) is measured using TOTO-1 excited

Atomic force microscopy is one of the few techniques that allow analysis of biological recognition processes at the single-molecule level. A major limitation of this approach is the nonspecific interaction between the force sensor and substrate. We h

High Speed Atomic Force Microscopy of Biomolecules by Image Tracking

Autor: Kees van der Werf, Bart G. de Grooth, S. John T. van Noort, Jan Greve

Publikováno v: Biophysical journal, 77(4), 2295-2303. Biophysical Society

An image-tracking procedure for atomic force microscopy is proposed and tested, which allows repeated imaging of the same area without suffering from lateral drift. The drift correction procedure is based on on-line cross-correlation of succeeding im

Single-Molecule Manipulation of Double-Stranded DNA Using Optical Tweezers: Interaction Studies of DNA with RecA and YOYO-1

Autor: Jan Greve, Martin L. Bennink, Bart G. de Grooth, Orlando D. Schärer, Kumiko Sakata‐Sogawa, Juleon M. Schins, Roland Kanaar, Johannes S. Kanger

By using optical tweezers and a specially designed flow cell with an integrated glass micropipette, we constructed a setup similar to that of Smith et al. (Science 271:795-799, 1996) in which an individual double-stranded DNA (dsDNA) molecule can be

Specific molecular recognition events, detected by atomic force microscopy (AFM), so far lack the detailed topographical information that is usually observed in AFM. We have modified our AFM such that, in combination with a recently developed method

Photon-counting device compatible with conventional flow cytometric data acquisition electronics

Autor: Alex Florians, Juleon M. Schins, Jan Greve, A. Agronskaia, Bart G. de Grooth, Kees van der Werf

Publikováno v: Cytometry, 32(3), 255-259. Wiley

We present an electronic scheme that enables us to use a photon-counting device (photomultiplier or avalanche photodetector) for measuring extremely weak signals in a flow cytometer. It can be used as a sole detector, or in combination with other (co

Height anomalies in tapping mode atomic force microscopy in air caused by adhesion

Autor: Kees van der Werf, Bart G. de Grooth, Niek F. van Hulst, Jan Greve, S. John T. van Noort

Publikováno v: Ultramicroscopy, 69(69), 117-127. Elsevier

Height anomalies in tapping mode atomic force microscopy (AFM) in air are shown to be caused by adhesion. Depending on the damping of the oscillation the height of a sticking surface is reduced compared to less sticking surfaces. It is shown that t

Why is the propagation velocity of a photon in a transparent medium reduced?

Autor: Bart G. de Grooth

Publikováno v: American journal of physics, 65(12), 1156-1164. American Association of Physics Teachers

A path integral formalism is used to describe the propagation of photons through a transparent medium. It is shown that the reduced phase velocity of light can be understood quantitatively by taking into account the contribution of all the possible c

The adsorption of high density lipoproteins (HDL) on polyethylene (PE), poly(2-hydroxyethyl methacrylate) (poly(HEMA)), polyesterurethane (PU), Biomer, and mica surfaces was studied. The adsorption of HDL from a single protein solution and a plasma s
