Autonomous Treatment of Bacterial Infections <i>in Vivo</i> Using Antimicrobial Micro- and Nanomotors Open
The increasing resistance of bacteria to existing antibiotics constitutes a major public health threat globally. Most current antibiotic treatments are hindered by poor delivery to the infection site, leading to undesired off-target effect…

Enzyme-Powered Porous Micromotors Built from a Hierarchical Micro- and Mesoporous UiO-Type Metal–Organic Framework Open
Here, we report the design, synthesis, and functional testing of enzyme-powered porous micromotors built from a metal-organic framework (MOF). We began by subjecting a presynthesized microporous UiO-type MOF to ozonolysis, to confer it wit…

Extraction of the propulsive speed of catalytic nano- and micro-motors\n under different motion dynamics Open
Motion of active particles, such as catalytic micro- and nano-motors, is\nusually characterized via either dynamic light scattering or optical\nmicroscopy. In both cases, speed of particles is obtained from the calculus of\nthe mean square…

Self-Propulsion of Active Colloids via Ion Release: Theory and Experiments Open
We study the self-propulsion of a charged colloidal particle that releases ionic species using theory and experiments. We relax the assumptions of thin Debye length and weak nonequilibrium effects assumed in classical phoretic models. This…

Ionic Species Affect the Self-Propulsion of Urease-Powered Micromotors Open
Enzyme-powered motors self-propel through the catalysis of in situ bioavailable fuels, which makes them excellent candidates for biomedical applications. However, fundamental issues like their motion in biological fluids and the understand…
