- Chemistry
- 1 November 2002
Numerous derivatives of BODIPY (4,4-difluoro-4-borata-3a-azonia-4a-aza-s-indacene) are frequently used as fluorescent probes in modern protein and lipid research. Present studies of… Expand
Diffusion and interaction in gels and solutions. 4. Hard sphere Brownian dynamics simulations
- L. Johansson, Jan-Erik Loefroth
- Chemistry
- 1 May 1993
Results from Brownian dynamics simulations of hard sphere diffusion in polymer networks of wormlike chains are presented. The influence of the size of the diffusing particles, the polymer… Expand
Diffusion and interaction in gels and solutions: I. Method
- L. Johansson, Jan-Erik Loefroth
- Chemistry
- 1 March 1991
Abstract A simple device based on a syringe has been evaluated for studies of diffusion in gels and solutions. A thorough description of the technique is given and the results from measurements of… Expand

Results are presented from Brownian dynamics simulations and from experimental measurements of self-diffusion coefficients of monovalent ions in systems of oppositely charged polymers. The… Expand
Linear Dichroism as a Tool for Studying Molecular Orientation in Membrane Systems. 2. Order Parameters of Guest Molecules from Linear Dichroism and Nuclear Magnetic Resonance
- L. Johansson, Å. Davidsson, G. Lindblom, B. Nordén
- Chemistry
- 1 November 1978
A linear dichroism (LD) method using macroscopically aligned samples was recently developed for studying biological model membranes. We show here that for these systems the influence from multiple… Expand
