Active Force Dynamics in Red Blood Cells Under Non-Invasive Optical Tweezers
Arnau Dorn, Clara Luque-Rioja, Macarena Calero +3
Red blood cells (RBCs) sustain mechanical stresses associated with microcirculatory flow through ATP-driven plasma membrane flickering. This is an active phenomenon driven by motor…

Stochastic motility energetics reveals cooperative bacterial swarming in optical tweezers
Clara Luque-Rioja, Horacio López-Menéndez, Macarena Calero +4
Bacterial flagellar swarming enables dense microbial populations to migrate collectively across surfaces, often resulting in emergent, coordinated behaviors. However, probing the u…

Optical control of spatially localized red blood cell activity by holographic tweezing
Niccolò Caselli, Mario García-Verdugo, Macarena Calero +4
Red blood cells possess unique biomechanical ability to squeeze through capillaries smaller than their size to enable gas and ion exchange. A key signature of their active biomecha…
