Stochastic modeling in nanoscale biophysics: Subdiffusion within proteins [PDF]

open access: yes, 2008
Advances in nanotechnology have allowed scientists to study biological processes on an unprecedented nanoscale molecule-by-molecule basis, opening the door to addressing many important biological problems. A phenomenon observed in recent nanoscale single-

Physics and the molecular revolution in plant biology: union needed for managing the future

open access: yesAIMS Biophysics, 2016
The question was asked if there is still a prominent role of biophysics in plant biology in an age when molecular biology appears to be dominating. Mathematical formation of theory is essential in systems biology, and mathematics is more inherent in ...

Non-Equilibrium Thermodynamic Approach to Ca2+-Fluxes in Cancer

open access: yesApplied Sciences, 2020
Living systems waste heat in their environment. This is the measurable effect of the irreversibility of the biophysical and biochemical processes fundamental to their life.

Biophysical Micromixer [PDF]

open access: yesSensors, 2009
In this study a biophysical passive micromixer with channel anamorphosis in a space of 370 mm, which is shorter than traditional passive micromixers, could be created by mimicing features of vascular flow networks and executed with Reynolds numbers ranging from 1 to 90.

Single Nanoparticle Tracking Reveals Efficient Long-Distance Undercurrent Transport in Upper Fluid of Bacterial Swarms

open access: yesiScience, 2019
Summary: Flagellated bacteria move collectively in a swirling pattern on agar surfaces immersed in a thin layer of viscous “swarm fluid,” but the role of this fluid in mediating the cooperation of the bacterial population is not well understood.

Differences in cortical contractile properties between healthy epithelial and cancerous mesenchymal breast cells

open access: yesNew Journal of Physics, 2021
Cell contractility is mainly imagined as a force dipole-like interaction based on actin stress fibers that pull on cellular adhesion sites. Here, we present a different type of contractility based on isotropic contractions within the actomyosin cortex ...

Edge-effects dominate copying thermodynamics for finite-length molecular oligomers

open access: yesNew Journal of Physics, 2021
A signature feature of living systems is their ability to produce copies of information-carrying molecular templates such as DNA. These copies are made by assembling a set of monomer molecules into a linear macromolecule with a sequence determined by the

Drugging Fuzzy Complexes in Transcription

open access: yesFrontiers in Molecular Biosciences, 2021
Transcription factors (TFs) are one of the most promising but underutilized classes of drug targets. The high degree of intrinsic disorder in both the structure and the interactions (i.e., “fuzziness”) of TFs is one of the most important challenges to be
