Metered passive flow enables controlled drug release without pumps or actuators — transdermal, implantable, and oral applications.
The Problem
Controlled drug release — whether transdermal, implantable, or inhaled — requires precise, repeatable fluid metering. Achieving this passively, without pumps or actuators, has been a fundamental challenge that limits the design space for next-generation drug delivery systems.
The Surnetics Solution
Gradient coatings enable precisely metered passive flow for drug delivery applications. Flow rate and stopping points are programmed into the coating design — enabling controlled, reproducible drug release without any active components.
Competitive Advantages
Flow rate and stopping points are programmed into the coating design — enabling reproducible, controlled drug release without active components.
Eliminates the mechanical complexity that limits miniaturization and reliability in conventional drug delivery devices.
Different gradient designs on the same device can deliver multiple drugs at different rates simultaneously.
Compatible with transdermal patches, implantable depots, inhalers, oral capsules, and microneedle arrays.
