    摘要: A new class of poly(beta-amino alcohols) (PBAAs) has been prepared using combinatorial polymerization. The inventive PBAAs may be used in biotechnology and biomedical applications as coatings (such as coatings of films or multilayer films for medical devices or implants), additives, materials, excipients, non-biofouling agents, micropatterning agents, and cellular encapsulation agents. When used as surface coatings, these PBAAs elicited different levels of inflammation, both in vitro and in vivo, depending on their chemical structures. The large chemical diversity of this class of materials allowed us to identify polymer coatings that inhibit macrophage activation in vitro. Furthermore, these coatings reduce the recruitment of inflammatory cells, and reduce fibrosis, following the subcutaneous implantation of carboxylated polystyrene microparticles. These polymers may be used to form polyelectrolyte complex capsules for cell encapsulation. The invention may also have many other biological applications such as antimicrobial coatings, DNA or siRNA delivery, and stem cell tissue engineering.

    摘要: In order to provide a golf ball with a water immersion indicator, a golf ball with indicia or a particular recognizable color is overlain with an opacification layer that provides a mask over the indicia or the colored ball until such time as the ball has been immersed in water for a predetermined period of time affecting the ball's performance. The opacification layer when removed or otherwise made transparent, while providing for a change in the appearance of the golf ball upon water immersion, does not need to have a layer or indicia which changes color in reaction to the infusion of water. Rather the opacification layer is either removed or made transparent to expose an underlying colored surface or a surface bearing pre-determined indicia, thus to alter the appearance of the ball when it has been immersed in water for a period of time which affects golf ball properties. The subject system provides an easy way to make indicia visible upon water immersion since one does not have to create the indicia in response to water activation, but rather uncover already-printed indicia due to the removal or transparency of the opacification layer. Opacification reduction or elimination is accomplished through a number of physical processes involving a water-activated binder and either insoluble pigment particles, effervescing bubbles, the use of transparent oils, agglomeration or the complete or partial removal of the opacification layer.

    摘要: Cosmetics represent a world-wide multi-billion dollar industry. The present invention provides technology for polymerizing monomers on skin in situ to produce desired skin characteristics. For example, the inventive system may be used to reduce the signs of aging or to protect the treated skin from UV light. The polymerization of monomers on skin is typically initiated using a thermal or photoinitiatied free radical initiator. In certain embodiments, the monomers are fluorinated thereby producing a fluorinated polymer on the skin upon polymerization. The invention provides monomers, initiators, methods, and kits for use in treating skin with polymers.
