The non-axisymmetric chiral squirmer [1], implemented within a Lattice Boltzmann code tailored for complex fluid dynamics [2], serves as a versatile tool to study the emergent behavior of microswimmer suspensions. Utilizing this model, we delve into the characterization of interactions between pairs of squirmers and explore their behavior in proximity to solid walls, as well as within the...
COMET-NANO leverages advances in nanotechnology to enhance catalysts at the nanoscale, essential in the chemical and environmental industries. The group develops hybrid nanosystems based on silica, titania, carbon nanotubes, graphene oxide, magnetite, metallic nanoparticles, and bismuth-based materials, with improved catalytic and photocatalytic properties through green chemistry.

Ultrasound-guided drug and gene delivery offers a non-invasive, high-precision, low-toxicity method for the controlled and spatially precise delivery of drugs and macromolecules, encapsulated in microbubbles and submicron gas vesicles, to targeted areas such as cancer tumors. This technique significantly reduces the drug dose while improving therapeutic efficacy. In this study, we present a...
Metabolic processes are crucial for sustaining life, involving the cyclic synthesis (anabolism) and degradation (catabolism) of chemical and supramolecular structures through the expense of chemical energy [1]. These highly dynamic structures which form under out-of-equilibrium (OOE) conditions define the hallmark features of life such as adaptivity and spatiotemporal control [2]. At the...
The atomic force microscope (AFM) is gaining progressive attention for its capability to provide maps of biophysical properties of adhered micro- and nanostructures at high spatial resolution (in the nanometre range), and in live conditions (buffers, cell media). In the biomedical community, these properties are much less explored than other type of characterization based on genetics and...
Cholesteric phases are liquid crystals in which a helical twist can be induced by the presence of a chiral agent. This twist, with a periodicity or pitch (p), can be frustrated under geometrical confinement comparable to p. Under those conditions, skyrmions can be formed if the material undergoes an instability. Skyrmions are topologically protected solitonic-like structures [1-3], formed by...
**Metal phosphates, a fascinating category of inorganic ring structures, have garnered considerable attention for their unique structural, physical, and chemical characteristics, including optical, electronic, and magnetic properties [1]. Cyclohexaphosphates, in particular, have attracted interest due to their high hydrolytic and thermal stabilities, as well as their strong complexation...
