Sensing in biological systems
… spiropyrans as effective sensors for biologically relevant metal ions relevant such as calcium (Ca²⁺) and zinc (Zn²⁺), as well as the alkali metals sodium (Na⁺), potassium (K⁺) and lithium (Li⁺). Chapter 2: In Chapter 2, we took a unique approach to Ca²⁺ sensing with a rationally …

Inertial manifolds in biological systems
The focus of this thesis is biological systems whose dynamics present an interesting feature: only some dimensions drive the whole system. In our examples, the dynamics is expressed as ODEs, such that the ith equation depends on all the variables xi = f (x1,...,xi,xi+1,...), so that they cannot be …

Computer Simulation of Biological Systems
This thesis investigates two biological systems using atomistic modelling and molecular dynamics simulation. The work is focused on: (a) the study of the interaction between a segment of a DNA molecule and a functionalized surface; (b) the dynamical modelling of protein tau, an intrinsically …

Modular design of biological systems
… development of technology for building compound biological systems from simpler pieces. I designed BioScaffold parts, a family of variable regions that can be inserted into a DNA sequence so that at a later time another set of pieces can be substituted for each variable. The variable regions are …

Phase transitions in fluids and biological systems
In this thesis, I consider systems from two seemingly different fields: fluid dynamics and microbial ecology. In these systems, the unifying features are the existences of global non-equilibrium steady states. I consider generic and statistical models for transitions between these global states, …

Stochastic processes in biological systems : selected problems
Majority of biological processes can not be described deterministically. Multple levels of regulation contribute to the noise in the observable properties of the cells: fluctuations are ubiquitous in biological networks and in their spatial organization. In this thesis we consider several examples …

Buckling instabilities of semiflexible filaments in biological systems
In dieser Arbeit werden Knickinstabilitäten von Filamenten in biologischen Systemen untersucht. Das Zytoskelett von Zellen ist aus solchen Filamenten aufgebaut. Sie sind für die mechanische Stabilität der Zelle verantwortlich und spielen eine große Rolle bei intrazellulären Transportprozessen durch …
