Application
Poloxamers are nonionic, triblock copolymers containg a central hydrophobic chain of poly(propylene glycol) (PPG) and two terminal hydrophilic chains of poly(ethylene glycol) (PEG). Due to their amphiphilic structure, poloxamer solutions feature temperature dependent self-assembling and thermo-gelling behavior. Concentrated aqueous solutions of poloxamers are liquid at low temperature and form a gel at higher temperature, in a reversible process. This characteristic has allowed for these materials to be used as drug carriers for most routes of administration including oral, topical, intranasal, ocular, and parenteral. Methacrylate-modified derivatives are most commonly used as thermosensitive hydrogels for drug delivery and 3D bioprinting applications. After casting or printing, the material can be crosslinked to preserve the hydrogel structure.

It is, sometimes, desirable to maintain a constant plasma drug concentration within the therapeutically effective concentration range. The use of high viscosity hydromiscible vehicles such as hydrophilic gels, is one of various approaches for controlled drug delivery, and represents an

Microvascular multinozzle arrays are designed and fabricated for high-throughput printing of functional materials. Ink-flow uniformity within these multigeneration, bifurcating microchannel arrays is characterized by computer modeling and microscopic particle image velocimetry (micro-PIV) measurements. Both single and dual multinozzle printheads are
