A new carbon nanotube porous silica poroshell stationary phase was developed. The chromatographic support was coated with ultrashort single-wall carbon nanotubes (SWCNTs) in a noncovalent way. It was demonstrated that the porous amino silica surface of the 300 NH2 poroshell column stabilized with 1-methyl-2-pyrrolidinone efficiently and stably adsorbed SWCNTs onto the chromatographic support. It was shown that this novel poroshell carbon nanotube (CNT) stationary phase was very useful for the HPLC separation of a series of monoclonal antibodies (mAbs) in a short analysis time (<3 min). The high-performance liquid chromatography (HPLC) method was validated and was successfully tested for the fast quantitative and qualitative control of chemotherapeutic bags fabricated in a hospital pharmacy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
