摘要:
Antimicrobial polymers, composition including the polymers, and methods of forming and using the polymers and compositions are disclosed. The compositions have reverse thermal gelling properties and transform from a liquid to a gel—e.g., near or below body temperature, such as a skin temperature in an operating room. The polymers and compositions can be applied to a surface, such as a surface of skin proximate an incision site prior to surgery, to provide a relatively sterile area near the site.
摘要:
The invention provides novel polymers, including triblock polymers, as well as methods of preparing the polymers, and compositions that include such polymers. The polymers can include at least three blocks, the first block that includes poly(styrene), the second block that includes a random arrangement of poly(ethylene) and poly(butylene), and a third block that includes functionalized poly(isoprene). Units of the functionalized poly(isoprene) block can include hydroxyl groups and one or more ether linked side chains comprising R1, R2, R3, R4, R5, R6, as defined herein, or a combination thereof. The polymers can be used to provide antifouling coatings, for example, for marine ship hulls.

摘要:
Biodegradable triblock copolymer compositions are provided which are useful in tissue engineering and drug delivery. The copolymers are reverse thermal gels in that when heated from a lower temperature to a higher temperature, they gel. These gels are useful in drug delivery when complexed with an active agent. For example the compositions can be used for intraocular injection of active agents, such as anti-angiogenic agents for treatment of a maculopathy or retinitis.
摘要:
Therapeutic agent delivery systems, which include a thermally-sensitive copolymer and optionally a therapeutic agent, are disclosed. The copolymer is water soluble and biodegradable and, in accordance with exemplary embodiments, includes hydrophobic and hydrophilic portions. The systems may include supplemental compounds, such as polymeric nanoparticles, micelle compounds, or a combination thereof, to further provide sustained release of the therapeutic agent.
摘要:
The invention provides novel compositions comprising one or more polymers, including a functional triblock copolymer and optionally a structural triblock copolymer and compositions that include such polymers. The functional triblock contains quaternized nitrogen anti-fouling functionality. The compositions can be used to prepare antimicrobial, antifouling coatings, for example, for medical, health, marine fouling, corrosion and general protein fouling resistance applications.
