| 摘要 |
Histochemical process compositions comprising at least one nanoparticle in an amount effective to reduce or substantially eliminate the average number of spots per slide that result from a sample staining protocol are disclosed. Various nanoparticles, or combinations thereof, including metals, metal alloys, metal oxides, ceramics, functionalized metals or metalloids, and other miscellaneous nanoparticles, such as carbon nanoparticles and diamond nanoparticles, can be used. The nanoparticle concentration typically is from about 2 parts per million to about 20 parts per million. One embodiment of a disclosed method concerns applying a histochemical process composition to a sample, followed by performing a staining protocol on the sample. Particular embodiments concern dispensing a nanosolution onto a sample using an automated system, heating the sample, and performing a sample staining process.
