Techniques to modify and apply aerogel coatings are described, including the application of spray-coated aerogels. The approach eliminates several of the wet chemical techniques previously needed for processes such as MALDI processing, and simplifies the automation of processes such as continuous monitoring in a sensor based format. With respect to MALDI processing, the preferred embodiment uses an acid-doped silica aerogel coated tape as the collection media as well as the matrix support. Although aerogels are disclosed as a preferred matrix material, other materials may alternatively be used, including linoleic acids, oleic acids, PEG (polyelthylene glycol), preferably in tape format.
介绍了气凝胶涂层的改性和应用技术,包括喷涂气凝胶的应用。这种方法省去了以前在 MALDI 处理等过程中所需的几种湿
化学技术,简化了以传感器为基础的连续监测等过程的自动化。在 MALDI 处理方面,优选实施方案使用掺酸
二氧化硅气凝胶涂层带作为收集介质和基质支撑。虽然气凝胶是作为优选基质材料公开的,但也可以使用其他材料,包括
亚油酸、
油酸、P
EG(聚
乙二醇),最好是胶带形式。
