一般描述
硅胶是胶体二氧化硅的刚性三维网络。它专门用作齐格勒-纳塔催化剂中活性钛（III）中心的载体材料。硅胶允许受控的碎裂，导致形成具有窄粒度分布和高堆积密度的均匀聚合物颗粒。硅胶分类如下：
a.水凝胶 - 孔内充满了水
b.干凝胶 - 通过蒸发过程，气孔中的水相被去除
c.气凝胶 - 通过超临界萃取去除溶剂

We have synthesized and characterized [18F]-N-(4-chloro-3-((fluoromethyl-d2)thio)phenyl)-picolinamide ([18F]15) as a potential ligand for the positron emission tomography (PET) imaging of mGluR4 in the brain. Radioligand [18F]15 displays central nervous system drug-like properties, including mGluR4 affinity, potent mGluR4 PAM activity, and selectivity
