Transient anomalous diffusion of tracer particles in soft matter
This paper is motivated by experiments in which time series of tracer particles in viscoelastic liquids are recorded using advanced microscopy. The experiments seek to infer either viscoelastic properties of the sample Mason and Weitz, Phys. Rev. Lett. 74, 1250–1253 1995 or diffusive properties of the specific tracer particle in the host medium Suh et al., Adv. Drug Delivery Rev. 57, 63–78 2005...
متن کاملChemotaxis-Induced Anomalous Tracer Diffusion in Bacterial Suspensions
By developing a molecular dynamics model of bacterial chemotaxis, we present the first investigation of tracer statistics in bacterial suspensions where chemotactic effects are considered. We demonstrate that the non-Gaussian statistics of full-coated tracer arises from the athermal bacterial noise. Moreover, Janus (half-coated) tracer performs a composite random walk combining powerlaw-tail di...
متن کاملAnomalous diffusion of Ibuprofen in cyclodextrin nanosponge hydrogels: an HRMAS NMR study
Ibuprofen sodium salt (IP) was encapsulated in cyclodextrin nanosponges (CDNS) obtained by cross-linking of β-cyclodextrin with ethylenediaminetetraacetic acid dianhydride (EDTAn) in two different preparations: CDNSEDTA 1:4 and 1:8, where the 1:n notation indicates the CD to EDTAn molar ratio. The entrapment of IP was achieved by swelling the two polymers with a 0.27 M solution of IP in D2O, le...
متن کاملSimulational Study of Cardiac Cell Contractility
This model was developed for the study of excitationcontraction coupling for single cardiac cell. The basic assumptions are following: depolarization of cellular sarkolemma (membrane) rises inward calcium current Is , which rises the level of sarcoplasmatic calcium but also induces release of calcium from cisternal sarcoplasmic reticulum. These two basic sources increase the level of sarcoplasm...
متن کاملTracer diffusion in active suspensions.
We study the diffusion of a Brownian probe particle of size R in a dilute dispersion of active Brownian particles of size a, characteristic swim speed U_{0}, reorientation time τ_{R}, and mechanical energy k_{s}T_{s}=ζ_{a}U_{0}^{2}τ_{R}/6, where ζ_{a} is the Stokes drag coefficient of a swimmer. The probe has a thermal diffusivity D_{P}=k_{B}T/ζ_{P}, where k_{B}T is the thermal energy of the so...
