Two instruments for liquid-phase synthesis of nanoparticles by high-temperature decomposition of organometallic precursors.
Two photoelectron correlation spectrometers (PCS ) (a Malvern Instruments ZETASI ZER 3000 HS and a Brookhaven 90PLUS PCS ) to obtain measurements of average hydrodynamic diameter, aggregate size distribution and isoelectric point of colloidal dispersions from nanoparticles.
Micromeritics ASA P 2020 analyzer to measure the specific surface area and porosity of nanoparticles and nanostructures by gas adsorption.
System for the thermal and optical characterization of core-shell metallic nanoparticles by surface plasmon resonance.
Software for data acquisition and processing from PCS , BET (for the interpretation of gas adsorption) and thermogravimetry.
The CVD machine grows both single and multiwalled carbon nanotubes, using both plasma-enhanced CVD (PECVD) and/or thermal CVD. It enables the production of advanced CNT Micro-Nano-Bio Systems (MNBS) for biological, chemical or biochemical analysis. As the suitability of the interface of any MNBS device is a critical point, the selective growth of CNT improves the electrode-electrolyte interface enhancing the biomonitoring.
Its specifications are:
›› Heat processing control up to 900ºC, with controlled ramps of up to 300ºC/min.
›› Plasma control; completely configurable source. Possibility of working without plasma.
›› Camera for 4” wafers.
›› Camera for following the process.
›› Possibility of processes in high vacuum (5 mBar) and at atmospheric pressure (800 mBar).
›› Process gases: hydrogen, methane, acetylene, argon,
ammonium and air.

Descripción: Automated analysis of the size distribution and concentration
The Malvern NanoSight NS300 uses the technology of Nanoparticle Tracking Analysis (NTA). This unique technology utilizes the properties of both light scattering and Brownian motion in order to obtain the size distribution and concentration measurement of particles in liquid suspension. A laser beam is passed through the sample chamber, and the particles in suspension in the path of this beam scatter light in such a manner that they can easily be visualized via 20x magnification microscope onto which is mounted a camera. The camera operates at 30 frames per second (fps), capturing a video file of the particles moving under Brownian motion. The software tracks many particles individually and using the Stokes-Einstein equation calculates their hydrodynamic diameters.
