Use of NMR to Test Molecular Mobility during Chemical Reaction
Huan Wang, Tian Huang, Steve Granick
We evaluate critically the use of pulsed gradient spin-echo nuclear magnetic resonance (PGSE NMR) to measure molecular mobility during chemical reactions. With raw NMR spectra avai…
Rapid-Prototyping a Brownian Particle in an Active Bath
Jin Tae Park, Govind Paneru, Chulan Kwon +2
Particles kicked by external forces to produce mobility distinct from thermal diffusion are an iconic feature of the active matter problem. Here, we map this onto a minimal model f…
Active phase separation by turning toward regions of higher density
Jie Zhang, Ricard Alert, Jing Yan +2
Studies of active matter, from molecular assemblies to animal groups, have revealed two broad classes of behavior: a tendency to align yields orientational order and collective mot…
Master curve of boosted diffusion for ten catalytic enzymes
Ah-Young Jee, Tsvi Tlusty, Steve Granick
Molecular agitation more rapid than thermal Brownian motion is reported for cellular environments, motor proteins, synthetic molecular motors, enzymes, and common chemical reaction…
Anatomy of cage formation in a 2D glass-forming liquid
Bo Li, Kai Lou, Walter Kob +1
The solidity of glassy materials is believed to be due to the cage formed around each particle by its neighbors, but in reality the details of cage-formation remain elusive [1-4].…
Robustness of FCS (Fluorescence Correlation Spectroscopy) with Quenchers Present
Hima Nagamanasa Kandula, Ah-Young Jee, Steve Granick
Inspired by recent publications doubtful of the FCS technique, we scrutinize how irreversible (static) and reversible (dynamic) quenching can influence the interpretation of such d…
Enhanced diffusion and enzyme dissociation
Ah-Young Jee, Kuo Chen, Tsvi Tlusty +2
The concept that catalytic enzymes can act as molecular machines transducing chemical activity into motion has conceptual and experimental support, but much of the claimed support…
Probing the Local Response of Glass-forming Liquids by Laser Excitations
Bo Li, Kai Lou, Walter Kob +1
The glass is a disordered solid that processes distinct dynamical and elastic properties compared with crystal. How heterogeneous glassy materials can be and to what extent dynamic…
The Effective Temperature Concept Tested in an Active Colloid Mixture
Ming Han, Jing Yan, Steve Granick +1
Thermal energy agitates all matter and its competition with ordering tendencies is one of the most fundamental organizing principles in the physical world. Thus, it is natural to e…
Natural selection in the colloid world: Active chiral spirals
Jie Zhang, Steve Granick
We present a model system in which to study natural selection in the colloid world. In the assembly of active Janus particles into rotating pinwheels when mixed with trace amounts…
Orientationally Glassy Crystals of Janus Spheres
Shan Jiang, Jing Yan, Jonathan K. Whitmer +3
Colloidal Janus spheres in water (one hemisphere attractive and the other repulsive) assemble into two-dimensional hexagonal crystals with orientational order controlled by anisotr…
Multiple Excitation of Confined Graphene Plasmons by Single Free Electrons
F. Javier Garcia de Abajo
We show that free electrons can efficiently excite plasmons in doped graphene with probabilities of order one per electron. More precisely, we predict multiple excitations of a sin…
Bursts of Active Transport in Living Cells
Bo Wang, James Kuo, Steve Granick
We scrutinize the temporally-resolved speed of active cargo transport in living cells, and show intermittent bursting motions. These nonlinear fluctuations follow a scaling law ove…
Single-Molecule Observation of Long Jumps in Polymer Adsorption
Changqian Yu, Juan Guan, Kejia Chen +2
Single-molecule fluorescence imaging of adsorption onto initially-bare surfaces shows that polymer chains need not localize immediately after arrival. In a system optimized to pres…
Diagnosing Heterogeneous Dynamics in Single Molecule/Particle Trajectories with Multiscale Wavelets
Kejia Chen, Bo Wang, Juan Guan +1
We describe a simple automated method to extract and quantify transient heterogeneous dynamical changes from large datasets generated in single molecule/particle tracking experimen…
Automated Line Tracking of lambda-DNA for Single-Molecule Imaging
Juan Guan, Bo Wang, Steve Granick
We describe a straightforward, automated line tracking method to visualize within optical resolution the contour of linear macromolecules as they rearrange shape as a function of t…
