In vitro cytotoxicity and in vivo distribution after direct delivery of PEG-camptothecin conjugates to the rat brain.
Low water solubility and rapid elimination from the brain inhibits local delivery via implants and other delivery systems of most therapeutic drugs to the brain. We have conjugated the chemotherapyExpand

Efficacy of camptothecin and polymer-conjugated camptothecin in tumor spheroids and solid tumors
Camptothecin (CPT) is an anti-cancer drug with low solubility in aqueous solutions, which limits its efficacy during chemotherapy. To bypass this problem, CPT was conjugated to poly(ethylene glycol)Expand

Conjugation to increase treatment volume during local therapy: a case study with PEGylated camptothecin.
Controlled release of chemotherapy drugs from polymer implants placed directly at the tumor site is a proven method for treatment of cancers of the brain. Although this method provides high doses ofExpand

Force Titration of Langmuir-Blodgett Bilayers of Glycine Amphiphiles: JKR-Type Measurements Using the Surface-Force Apparatus
Using the surface-force apparatus, we have made Johnson-Kendall-Roberts (JKR)-type adhesion measurements between Langmuir-Blodgett (LB) bilayers of a novel glycine amphiphile. The bilayers show aExpand
