Extracting hydrogel properties by watching hydrogel particles moving through solid ice
Yanxia Feng, Se-Hyeong Jung, Camillo Sirvinski +4
Strikingly, when hydrogel particles are embedded in ice in a temperature gradient, they move through the solid ice towards warmer temperatures, while swelling as they warm up. This…
Label-free quantitative imaging of two-dimensional concentration gradients using Fabry-Pérot interferometry
Taieesa Peshkovsky, Stefan Andreas Schmid, David Taylor +3
Concentration gradients at the microscale play a central role in many physical, chemical, and biological systems, yet their quantitative visualization remains challenging due to th…
Density modulations in active colloidal systems through orthogonal propulsion control and sensory delays
Ueli Töpfer, Maximilian R. Bailey, Sanjay Schreiber +2
Recent advancements in active colloidal systems aim to mimic key characteristics of biological microswimmers, particularly their adaptive motility in response to environmental chan…
Janus microswimmers are poor hydrodynamic mixers
Maximilian Bailey, Dmitry Fedosov, Federico Paratore +3
The generation of fluid flows by autophoretic microswimmers has been proposed as a mechanism to enhance mass transport and mixing at the micro- and nanoscale. Here, we experimental…
Gate Electrodes Enable Tunable Nanofluidic Particle Traps
Philippe M. Nicollier, Aaron D. Ratschow, Francesca Ruggeri +4
The ability to control the location of nanoscale objects in liquids is essential for fundamental and applied research from nanofluidics to molecular biology. To overcome their rand…
Dynamic control of high-voltage actuator arrays by light-pattern projection on photoconductive switches
Vesna Bacheva, Amir Firouzeh, Edouard Leroy +7
The ability to control high-voltage actuator arrays relies, to date, on expensive microelectronic processes or on individual wiring of each actuator to a single off-chip high-volta…
Shaping liquid films by dielectrophoresis
Israel Gabay, Federico Paratore, Evgeniy Boyko +3
We present a theoretical model and experimental demonstration of thin liquid film deformations due to a dielectric force distribution established by surface electrodes. We model th…
Electroosmotic flow dipole: experimental observation and flow field patterning
Federico Paratore, Evgeniy Boyko, Govind V. Kaigala +1
We experimentally demonstrate the phenomenon of electroosmotic dipole flow that occurs around a localized surface charge region under the application of an external electric field…
