A method for producing mesoporous platinum nanoparticles without using templating agents is provided. The method involves preparing a solution comprising water, platinum nanoparticle seeds, a platinum salt and a reducing agent, and heating the solution to a temperature between 150° C. and 250° C. at a rate of between 1° C./min and 15° C./min under a pressure of between 5 and 20 atm. The method allows obtaining mesoporous platinum nanoparticles having controlled shape and controlled pore dimensions. The mesoporous platinum nanoparticles are useful as catalysts in chemical precision reactions and for the production of artificial enzymes for diagnostics and nanomedicine applications.

Method for the synthesis of mesoporous platinum nanoparticles in an aqueous environment

Imaging method for a biological sample using microscopy, for example fluorescence optical microscopy, electron microscopy, or correlative microscopy, which provides to use imaging probes to obtain images in which it is possible to identify the imaging probes and/or possible molecules associated with them. The present invention also concerns the imaging probes, possibly functionalized, that can be used both in CLEM experiments and also in immunocytochemical experiments.

Method for imaging a biological sample and corresponding probe

The present disclosure relates to a seed-growth based method for the synthesis of metal nanoparticles of controlled shape (cubes, cuboids, octahedrons) and size in an aqueous environment, without the use of shape directing agents. The method involves a first step of preparing a solution comprising water, metal seed growth nanoparticles, a metal salt comprising the same metal as the metal seed growth nanoparticles, and a reducing agent; and a second step of heating the solution to between 9 and 130&#xb0; C. at a rate of between 1&#xb0; C./min and 5&#xb0; C./min and at a pressure of between 1 and 5 atm. The method may also be carried out in a reduced oxygen atmosphere and the concentration of oxygen disclosed in the solution may be less than the concentration of oxygen in an oxygen saturated solution.
