Delivery systems specifically engineered to administer advanced drug formulations (e.g., microparticles, biologics, extended-release systems) to achieve precise targeting, controlled release kinetics, or enhanced therapeutic efficacy within the body.
Mechanical or electromechanical systems designed for precise, often self-administered, delivery of medicaments, including features for dose setting, needle insertion/retraction, and safety mechanisms to prevent premature activation.
Development of adhesive compositions that are applied in a molten state and solidify upon cooling, focusing on specific polymer blends, additives, and their resulting mechanical or optical properties.
Multi-layer polymer films engineered to provide superior barrier properties against gases (e.g., oxygen), moisture, or aromas, often incorporating heat-sealing or resealing mechanisms for food and product preservation.
Adhesive compositions specifically formulated to bind active materials within battery electrodes, emphasizing properties like electrolyte resistance, adhesion to current collectors, and processability for manufacturing.
Adhesive technologies focused on environmental benefits such as biodegradability, natural origin, or designed for easy debonding and re-bonding to facilitate recycling, reuse, or specific application needs.
Materials added to polymers to modify their thermal transfer properties, typically increasing conductivity for heat dissipation in applications like electronics or battery packs.
Thin, multi-layered films and structures specifically designed for electronic applications, including flexible substrates for devices, display panel components, and active material layers for battery electrodes.
