Abstract
A system for producing dry nanoparticles from a liquid includes a closed tubing system which incorporates a mister, heater and an electrostatic collector therein. The system is able to produce dry nanoparticles from liquid-suspensions and from solvent solutions.
Claims20
A system for drying liquid-suspended nanoparticles comprising:
- a closed tubing system including an access port for receiving a liquid solution therein, wherein the liquid solution contains suspended nanoparticles therein;
- a mister for transforming the liquid solution into an aerosol containing droplets, wherein the droplets contain liquid and suspended nanoparticles;
- a heater for heating a first portion of the closed tubing system, creating an updraft therein, and causing the aerosol to move through at least a second portion of the closed tubing system and further causing the evaporation of at least some liquid from the droplets in the aerosol, thereby leaving dried nanoparticles;
- and
- an electrostatic collector comprised of one or more electrodes located in a third portion of the closed tubing system, wherein the dried nanoparticles are collected at the one or more electrodes of the electrostatic collector as the aerosol flows therethrough.

A system for creating dry nanoparticles from a solution comprising:
- a closed tubing system including an access port for receiving the solution therein, wherein the solution contains materials therein for forming nanoparticles;
- a mister for transforming the solution into an aerosol containing droplets, wherein the droplets contain solvent and the materials therein;
- a heater for heating a first portion of the closed tubing system, creating an updraft therein, and causing the aerosol to move through at least a second portion of the closed tubing system and further causing the evaporation of at least some liquid from the droplets in the aerosol and formation of dried nanoparticles from the materials;
- and
- an electrostatic collector comprised of one or more electrodes located in a third portion of the closed tubing system, wherein the dried nanoparticles are collected at the one or more electrodes of the electrostatic collector as the aerosol flows therethrough.
