7 p, 5.3 MB Improving catalase-based propelled motor endurance by enzyme encapsulation / Simmchen, Juliane (Institut Català de Nanociència i Nanotecnologia) ; Baeza, Alejandro (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Ruiz-Molina, Daniel (Institut Català de Nanociència i Nanotecnologia) ; Vallet Regí, María (Universidad Complutense de Madrid. Departamento de Química Inorgánica)
Biocatalytic propulsion is expected to play an important role in the future of micromotors as it might drastically increase the number of available fuelling reactions. However, most of the enzyme-propelled micromotors so far reported still rely on the degradation of peroxide by catalase, in spite of being vulnerable to relatively high peroxide concentrations. [...]

8 p, 1.4 MB Synthesis of Polydopamine-Like Nanocapsules via Removal of a Sacrificial Mesoporous Silica Template with Water / Nador, Fabiana (Institut Català de Nanociència i Nanotecnologia) ; Guisasola, Eduardo (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Baeza, Alejandro (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Moreno Villaécija, Miguel Ángel (Institut Català de Nanociència i Nanotecnologia) ; Vallet Regí, María (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Ruiz-Molina, Daniel (Institut Català de Nanociència i Nanotecnologia)
Hollow polymeric polydopamine (PDA) micro-/nanocapsules have been obtained through a very simple, mild, and straightforward method that involves coating of silica mesoporous nanoparticles through an ammonia-triggered polymerization of PDA and the posterior removal of the sacrificial template simply by dispersion in water, without the need of any harsh chemical reagent, either in the presence or absence of active principles, from doxorubicin to iron oxide nanoparticles.

9 p, 1.5 MB Dynamics of novel photoactive AgCl microstars and their environmental applications / Simmchen, Juliane (Institut Català de Nanociència i Nanotecnologia) ; Baeza, Alejandro (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Miguel López, Albert (Institut de Bioenginyeria de Catalunya) ; Stanton, Morgan M. (Max-Planck-Institut für Intelligente Systeme) ; Vallet Regí, María (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Ruiz-Molina, Daniel (Institut Català de Nanociència i Nanotecnologia) ; Sánchez, Samuel (Institut de Bioenginyeria de Catalunya)
In the field of micromotors many efforts have been taken to find a substitute for peroxide as fuel. While most approaches turn towards other toxic high energy chemicals such as hydrazine, we introduce here an energy source that is widely used in nature: light. [...]

34 p, 1002.4 KB Polydopamine-like Coatings as Payload Gatekeepers for Mesoporous Silica Nanoparticles / Moreno Villaécija, Miguel Ángel (Institut Català de Nanociència i Nanotecnologia) ; Sedó Vegara, Josep (Institut Català de Nanociència i Nanotecnologia) ; Guisasola, Eduardo (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Baeza, Alejandro (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Vallet Regí, María (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Nador, Fabiana (Universidad Nacional del Sur) ; Ruiz-Molina, Daniel (Institut Català de Nanociència i Nanotecnologia)
We report the use of bis-catecholic polymers as candidates for obtaining effective, tunable gatekeeping coatings for mesoporous silica nanoparticles (MSNs) intended for drug release applications. In monomers, catechol rings act as adhesive moieties and reactive sites for polymerization, together with middle linkers which may be chosen to tune the physicochemical properties of the resulting coating.

IFW Dresden) ; Sanchez, Samuel (Max-Planck-Institut für Intelligente Systeme) ; Chokmaviroj, Sarocha (Chulalonkorn University) ; Ruiz-Molina, Daniel (Institut Català de Nanociència i Nanotecnologia) ; Baeza, Alejandro (Universidad Complutense de Madrid. Departamento de Química Inorgánica) ; Schmidt, Oliver G. (Institut für Integrative Nanowissenschaften. IFW Dresden)
The development of artificial micromotors is one of the greatest challenges of modern nanotechnology. Even though many kinds of motors have been published in recent times, systematic studies on the influence of components of the fuel solution are widely missing. [...]

133 p, 7.1 MB Movement at the nanoscale : catalytically and light driven micromotors / Simmchen, Juliane ; Ruiz-Molina, Daniel, dir. ; Baeza, Alejandro, dir. ; Universitat Autònoma de Barcelona. Departament de Química
Durante la ultima decada la creación de movimiento a la escala micro y nano ha evolucionado mucho y se ha convertido en un campo que connecta varias disciplinas de la ciencia. En su breve historia han sido la engeneria y la quimica las disciplinas leaderes, pero hoy en dia muchos impulsos vienen de la ciencia de materiales y la biotecnologia. [...]
In the last decade the generation of movement at the microscale has evolved to a fascinating new field of that connects several fields of modern science. In its short history mainly engineering and chemistry were dominating the research in this area but lately many novel inputs were given by biotechnology or material science. [...]
