一般說明

聚（丙烯酸）（PAA）在自然状态下具有吸湿性、脆性和且无色，Tg接近106oC。在高于200至250oC的温度下，它会失水并变成不溶的交联聚合物酸酐。干燥的PAA在水中的溶解度会随着温度的升高而提高。PAA在水中的浓缩液在自然状态下是具有触变性的。

應用

PAA的应用可包括：
  • 研究聚乙烯醇/PAA共聚物水凝胶中的溶质扩散
  • 合成可对温度和pH刺激产生相应的聚（N-异丙基丙烯酰胺）-嵌段-PAA共聚物
  • 作为粘合剂的增稠剂用于疏水性药物胶束递送的低聚（甲基丙烯酸甲酯）/PAA的嵌段共聚物的制备
  • 。

Novel Inks for Direct-Write Assembly of 3-D Periodic Structures

New methods for materials fabrication at the micro- and nanoscale will drive scientific and technological advances in areas of materials science, chemistry, physics, and biology. The broad diversity of potentially relevant materials, length scales, and architectures underscores the need for flexible patterning approaches. One important example is the fabrication of 3D periodic structures composed of colloidal, polymeric, or semiconductor5 materials.

Magnetic-Plasmonic Hybrid Nanobeads Designed for Imaging and Isolation of Cellular Organelles

Magnetic-plasmonic nanoparticles offer the combined benefits of both a magnetic probe as well as additional imaging modes usually associated with noble metal nanoparticles. Professor Shinya Maenosono (Japan Advanced Institute of Science and Technology) explores the synthesis, characterization, and proof-of-concept application of Ag/FeCo/Ag core/shell/shell magnetic-plasmonic nanobeads for imaging and isolation of cellular organelles (autophagosomes of COS-1 cells).
