In a method and device for separating components in a corona discharge zone an air stream containing water molecules is passed between at least one ionizing electrode and at least one non-ionizing electrode; and high voltage is applied to the electrodes to create a corona discharge zone consisting of a plasma region wherein ozone is formed and a dark region where predominantly hydrogen peroxide is formed. The air flow entering the corona discharge zone is divided into two separate air flows, a first of which passes through the corona discharge plasma region, and a second of which passes through the dark corona discharge region; and a negative pressure gradient is applied to the plasma region only so as to remove the ozone and thereby separate the ozone from the hydrogen peroxide.

Apparatuses and methods for delivering bioactive substances or cosmetic substances using plasmaporation and microneedles are provided. The delivery of the substances includes topical, intracellular, intercellular, and transdermal delivery to the subject.

This invention relates generally to novel methods and novel devices for the continuous manufacture of nanoparticles, microparticles and nanoparticle/liquid solution(s). The nanoparticles (and/or micron-sized particles) comprise a variety of possible compositions, sizes and shapes. The particles (e.g., nanoparticles) are caused to be present (e.g., created) in a liquid (e.g., water) by, for example, preferably utilizing at least one adjustable plasma (e.g., created by at least one AC and/or DC power source), which plasma communicates with at least a portion of a surface of the liquid. At least one subsequent and/or substantially simultaneous adjustable electrochemical processing technique is also preferred. Multiple adjustable plasmas and/or adjustable electrochemical processing techniques are preferred. The continuous process causes at least one liquid to flow into, through and out of at least one trough member, such liquid being processed, conditioned and/or effected in said trough member(s). Results include constituents formed in the liquid including micron-sized particles and/or nanoparticles (e.g., metallic-based nanoparticles) of novel size, shape, composition and properties present in a liquid.

A reactor for forming a plasma in a flowing fluid that includes a central rod belonging to a first electrode, an insulator, a tubular body belonging to a second electrode and defining a cylindrical space for the flow of the fluid between the tubular body and the insulator. The reactor further includes control disk having a front face linked to a downstream end of the central rod, and a permanent magnet juxtaposed against a back face of the control disk. One or more ribs are on a front face of the control disk according to a pattern in relief defining successive starting points for an electric arc distributed around the central axis of the reactor so as to generate electric arcs situated on a reaction cone and appearing to turn around the central axis.

A corona/plasma treatment machine includes an array of electrodes arranged in a helix along a conductive central cylinder, allowing for the efficient surface treatment of materials with greater cross-sectional heights and widths than what is conventionally possible. The corona/plasma treatment machine further includes of a high frequency, high voltage power source, a dielectric, and a contact plate. The array of electrodes is driven using a motor and rotates about its longitudinal axis and is electrically isolated from its surroundings. When power is supplied to the electrode array, electrical energy is discharged from the tips of the electrodes near the contact plate and creates a plasma corona aura formed from the ionization of the surrounding air between the electrode array and the contact plate. A conveyor is positioned below the electrode array and configured to feed material through the plasma corona aura.
