The present invention discloses the use of a metal nanoparticle which comprises at least one semiconductor attached to it, wherein the at least one semiconductor is an atomic quantum cluster (AQC) consisting of between 2 and 55 zero-valent transition metal atoms, as photocatalysts in photocatalytic processes and applications thereof.

Photoconversion of light using metal supported atomic quantum clusters

The present invention relates to nanosystems comprising metal atomic quantum clusters (AQCs) of at least two different sizes encapsulated in a cavity with an inner diameter less than or equal to 10 nm for the use thereof as luminescent nanosystems, particularly for the use thereof as fluorescent nanosystems; as well as the method for obtaining and detecting them. The invention also relates to the use of said luminescent nanosystems as a fluorescent probe, biomarker or contrasting agent.

Luminescent nanosystems

The present invention relates to the use of nanosystems as non deactivable security markers comprising metal atomic quantum clusters (AQCs) of at least two different size distributions encapsulated in a cavity with an inner diameter less than or equal to approximately 10 nm. These nanosystems are luminescence, particularly fluorescence after external excitation. The invention also relates to security documents, articles or elements incorporating these markers as well as to a method and a system for detecting the same.

Use of luminescent nanosystems for authenticating security documents

Stable atomic quantum clusters, AQCs, characterized by being composed of at least 500 metal atoms, its production process characterized by having a kinetic control and by maintaining a low concentration of reagents in the reaction medium, as well as the uses of these clusters as sensors (fluorescent, magnetic or chemical), electrocatalysts and as cytostatics and/or cytotoxics.

Stable atomic quantum clusters, production method thereof and use of same

The invention relates to conductive inks obtained by combining AQCs and metal nanoparticles. Atomic quantum clusters (AQCs), which melt at temperatures of less than 150&#xb0; C., are used as low-temperature 'flux' for the formulation of conductive inks. The combination of AQCs with bimodal and trimodal mixtures of nanoparticles of various sizes guarantees the elimination of free volumes in the final sintering of the nanoparticles in order to achieve electronic structures with very low resistivity (close to that of the bulk material) with low-temperature thermal treatments (&#x3c;150&#xb0; C.).

Conductive inks obtained by combining AQCs and metal nanoparticles

The invention relates to the use of stable atomic quantum clusters (AQC) with antimicrobial activity. The stable AQCs include at least 500 metal atoms (Mn, n&#x3c;500), the metals being selected from among Au, Ag, Co, Cu, Pt, Fe, Cr, Pd, Ni, Rh, Pb or bi- or multi-metallic combinations thereof. Said AQCs are used as antimicrobial agents, antifungal agents and biocides at concentrations of the order of between 1 nM and 100 nM or more in relation to atoms of the corresponding metal. The antimicrobial activity is specific to both the type of metal and size of cluster used.

Use of atomic quantum cluster (AQC) as antimicrobial agents and biocides

The present invention relates to nanocompounds comprising a charge-transfer complex of at least two different size metal atomic quantum clusters (AQCs) and the use thereof as luminescent nanocompounds, particularly for the use thereof as fluorescent nanocompounds; as well as the method for obtaining and detecting them.

Luminescent nanocompounds

The present invention relates to the use of nanocompounds as non deactivable security markers comprising a charge-transfer complex of at least two different size metal atomic quantum clusters (AQCs). These nanocompounds are luminescent, particularly fluorescent after external excitation. The invention also relates to security documents, articles or elements incorporating these markers as well as to a method and a system for detecting the same.

Use of luminescent nanocompounds for authenticating security documents

The present invention relates to a new method for preparing anisotropic metal nanoparticles with high aspect ratios and different types of structures by means of catalysis by Atomic Quantum Clusters (AQCs).

Process for preparing anisotropic metal nanoparticles

Process to obtain ultra fine magnetic Nd-Fe-B particles of various sizes, which can cause a reaction in different kinetic conditions, between compounds of Nd, Fe and B in the sine of micro-emulsions formed by water, oil and a surface-active agent, in different thermodynamic conditions.
