Continuous Plasma Attachment of Bacteriophages on Small Particles

The patent implements a continuous manufacturing process where small particles are conveyed through a plasma treatment zone and then immediately contacted with bacteriophage solution. This continuous flow system eliminates the batch processing steps, maintaining reliable attachment through consistent plasma activation while dramatically increasing productivity by processing particles continuously rather than in discrete batches.

The patent replaces mechanical batch mixing and attachment methods with a plasma-based activation system. The plasma treatment creates reactive surface groups on particles in a controlled manner, enabling reliable bacteriophage attachment through chemical activation rather than mechanical mixing, while the continuous conveyance system enables high-throughput processing.

The patent changes the surface parameter of particles by applying plasma treatment, which modifies surface chemistry and charge characteristics. This parameter change neutralizes problematic electrostatic effects while maintaining process simplicity, as the plasma treatment is applied automatically during continuous conveyance without requiring additional manual intervention.

The plasma treatment acts as an intermediary step between particle conveyance and bacteriophage contact. It mediates the interaction by creating a controlled surface state that eliminates uncontrolled electrostatic dispersion or clumping, ensuring reliable attachment while keeping the overall process simple through automated integration.

The patent uses periodic or pulsed plasma discharge rather than continuous discharge. This periodic activation provides sufficient surface modification for reliable bacteriophage adhesion while allowing charge dissipation between pulses, preventing static charge build-up that would cause particle dispersion. The pulsed nature maintains adhesion reliability while eliminating the harmful electrostatic effects.

The patent converts the potentially harmful electrostatic charge build-up into a beneficial controlled surface activation. By using plasma treatment with controlled parameters, the electrostatic effects are harnessed to create reactive surface groups that improve bacteriophage adhesion, while the continuous conveyance and controlled discharge prevent uncontrolled charge accumulation that would cause dispersion.
