New Nanoparticles Study Findings Have Been Reported from Jiangnan University (Functionalized Mesoporous Silica Nanoparticles with Mucoadhesive and Sustained Drug Release Properties for Potential Bladder Cancer Therapy)

By a News Reporter-Staff News Editor at Cancer Weekly -- Researchers detail new data in Nanoparticles. According to news reporting out of Wuxi, People's Republic of China, by NewsRx editors, research stated, "The synthesis of a series of beta-cyclodextrin modified mesoporous silica nanoparticles with hydroxyl, amino, and thiol groups was described. A comparison of their mucoadhesive properties and potential as a drug delivery system for superficial bladder cancer therapy was made."

Our news journalists obtained a quote from the research from Jiangnan University, "The thiol-functionalized nanoparticles exhibit significantly higher mucoadhesivity on the urothelium as compared to the hydroxyl- and amino-functionalized nanoparticles. This is attributed to the formation of disulfide bonds between the thiol-functionalized nanoparticles and cysteine-rich subdomains of mucus glycoproteins. An anticancer drug, doxorubicin, was loaded into the mesopores of the thiol-functionalized nanoparticles, and sustained drug release triggered by acidic pH was achieved."

According to the news editors, the research concluded: "The present study demonstrates that thiol-functionalized mesoporous silica nanoparticles are promising as a mucoadhesive and sustained drug delivery system for superficial bladder cancer therapy."
