Enzymatic reactions can consume endogenous nutrients of tumor and produce cytotoxic species, therefore are promising tools for treating malignant tumors. Inspired by nature that enzymes are compartmentalized in membranes to achieve high reaction efficiency and separate biological processes with the environment, we develop liposomal nanoreactors tha...

Hypothesis The internal organization of polyelectrolyte layers deposited on colloidal templates plays a very important role for the potential applications of these systems as capsules for drug delivery purposes. Experiments The mutual arrangement of oppositely charged polyelectrolyte layers upon their deposition on positively charged liposomes h...

As liposomes have been widely explored as drug delivery carriers over the past decades, they are one of the most promising platforms due to their biocompatibility and versatility for surface functionalization. However, to improve the specific design of liposomes for future biomedical applications such as nanovaccines, it is necessary to understand...

The use of the Layer-by-Layer (LbL) method for the fabrication of structural and functional materials through the alternate deposition of polyelectrolyte bearing opposite charges has undergone a spectacular development due to the numerous avenues that offer for controlling the assembly process by simply tuning some operational parameters or charact...

Polyelectrolyte multilayered capsules (PEMUCs) obtained using the Layer-by-Layer (LbL) method have become powerful tools for different biomedical applications, which include drug delivery, theranosis or biosensing. However, the exploitation of PEMUCs in the biomedical field requires a deep understanding of the most fundamental bases underlying thei...

In this work we introduce a modular self-assembled microswimmer whose propulsion mechanism along a fluid interface is based on the decoupling between the dynamics exhibited by the component particles and the assembly. The velocity, direction, and structure of the array can be dynamically adjusted by altering the applied field and understood in term...

The application of static or precessing magnetic fields on superparamagnetic colloids confined at fluid interfaces induces the formation of different self‐assembled structures, mainly determined by the field tilt angle. In article number 2101188, Fernando Martínez‐Pedrero, Carles Calero, and co‐workers demonstrate that dynamic bead‐like structures...

The coating of liposomes by the deposition of polyelectrolyte multilayered films using the layer-by-layer approach can be modulated by changing the charge of the nude liposome. This methodology provides a very promising tool for encapsulation and protection of drugs with different hydrophilicity/hydrophobicity (cover art designed by Patricia Guisad...

Magnetic colloids adsorbed at a fluid interface are unique model systems to understand self-assembly in confined environments, both in equilibrium and out of equilibrium, with important potential applications. In this work the pearl-chain-like self-assembled structures of superparamagnetic colloids confined to a fluid-fluid interface under static a...

The Layer-by-Layer (LbL) method is a well-established method for the assembly of na-nomaterials with controlled structure and functionality through the alternate deposition onto a template of two mutual interacting molecules, e.g., polyelectrolytes bearing opposite charge. The current development of this methodology has allowed the fabrication of a...

In article number 1900239, Fernando Martínez‐Pedrero and co‐workers demonstrate vesicles containing magnetic nanowires that combine the transport at will of microscopic systems, the protection conferred by the phospholipid membrane, and the required flexibility to deform during passage through microscale openings.

In this work, two real-time methods to transport magnetic nanowires confined in giant hybrid vesicles upon the application of different strategies are studied. The microscale carriers are either magnetically guided through the viscous medium by a non-homogenous field or advected by precisely monitored hydrodynamic flows. The slender geometry of the...

Some biological microorganisms can crawl or swim due to coordinated motions of their cytoskeleton or the flagella located inside their bodies, which push the cells forward through intracellular forces. To date, there is no demonstration of a biomimetic self-propelled swimmer operating at a low Reynolds number due to internal movements within an enc...

Soft assemblies obtained following the Layer-by-Layer (LbL) approach are accounted among the most interesting systems for designing biomaterials and drug delivery platforms. This is due to the extraordinary versatility and flexibility offered by the LbL method, allowing for the fabrication of supramolecular multifunctional materials using a wide ra...

The adsorption of polyelectrolytes onto charged surfaces plays a central role in many technological areas, including: modification of adhesion and wetting, increase of lubrication and friction reduction. The careful control of the processes involved in the polyelectrolyte adsorption onto solid surfaces is essential for the development of applicatio...
