我们提出一种制造工艺来制备双功能微粒,这些微粒展示两种不同的蛋白质,它们在空间上分隔在半球表面。直径为2.0μm、4.1μm和4.7μm的二氧化硅和聚苯乙烯微粒经过金属沉积处理,形成两个化学性质不同且分隔的半球。然后,使用不同的化学偶联策略,用生物蛋白质分别对每个半球的表面进行衍生化。这些双功能的雅努斯粒子具有生物相关的、天然构象的蛋白质,这些蛋白质附着在生物无反应且安全的基质上。它们还展示出每种蛋白质的高密度,这可能使它们具备一系列单功能粒子无法实现的能力,例如改进药物和生物成像剂的靶向性。
We present a fabrication process to create bifunctional microparticles displaying two distinct proteins that are spatially segregated onto the surface hemispheres. Silica and polystyrene microparticles with 2.0 μm, 4.1 μm, and 4.7 μm diameters are processed with metal deposition to form two chemically distinct and segregated hemispheres. The surface of each hemisphere is then separately derivatized with biological proteins using different chemical conjugation strategies. These bifunctional Janus particles possess biologically relevant, native conformation proteins attached to a biologically-unreactive and safe substrate. They also display high densities of each type of proteins which may enable a range of capabilities that monofunctional particles cannot, such as improved targeting of drugs and bioimaging agents.
