Dear Saeed, in dentistry we use a lot of this class of chemicals, mainly silver nanoparticles as disinfectant agents. I hope it is usefull to your question.

Liposoms, Polymeric self-assembling micelles, Drug-polymer conjugates, etc.

Check these Review articles on cancer therapy

Search for nanoparticles at www.clinicaltrials.gov and you will find 181 trials
