DNA damage induced by micellar-delivered doxorubicin and ultrasound: comet assay study
(Elsevier, 2000)To minimize adverse side effects of chemotherapy, we have developed a micellar drug carrier that retains hydrophobic drugs, and then releases the drug by ultrasonic stimulation. This study investigated the DNA damage induced ... -
Factors affecting acoustically triggered release of drugs from polymeric micelles
(Elsevier, 2000)A custom ultrasonic exposure chamber with real-time fluorescence detection was used to measure acoustically-triggered drug release from Pluronic P-105 micelles under continuous wave (CW) or pulsed ultrasound in the frequency ... -
Stabilization of Pluronic P-105 Micelles with an Interpenetrating Network of N,N-Diethylacrylamide
(American Chemical Society, 2000)N,N-Diethylacrylamide (NNDEA) was polymerized in the presence of Pluronic P-105 micelles. The polymerizations resulted in an interpenetrating network of poly(NNDEA) and P-105 that stabilized the micelles at concentrations ... -
Kinetics of ultrasonic release of doxorubicin from pluronic P105 micelles
(Elsevier, 2001)The aim of this research was to measure and model the kinetics of acoustic release and subsequent re-encapsulation of Doxorubicin (DOX) from Pluronic P105 micelles. A fluorescence detection ultrasound exposure chamber was ... -
Intracellular uptake of Pluronic copolymer: effects of the aggregation state
(Elsevier, 2002)The effect of the Pluronic P-105 aggregation state on its uptake by HL-60 cells was studied by flow cytometry, fluorescence spectroscopy, and confocal and fluorescence microscopy using a fluorescently labeled Pluronic P105. ... -
Ultrasonic release of doxorubicin from Pluronic P105 micelles stabilized with an interpenetrating network of N,N diethylacrylamide
(Elsevier, 2002)Pluronic P105 micelles sequester hydrophobic drugs and release them upon insonation with low frequency ultrasound; however these micelles dissolve relatively quickly upon dilution. The objective of this research was to ... -
Investigating the mechanism of acoustically activated uptake of drugs from Pluronic micelles
(BioMed Central (BMC), 2002)Background: This paper examines the mechanism of ultrasonic enhanced drug delivery from Pluronic micelles. In previous publications by our group, fluorescently labeled Pluronic was shown to penetrate HL-60 cells with and ... -
Drug delivery in pluronic micelles: effect of high-frequency ultrasound on drug release from micelles and intracellular uptake
(Elsevier, 2002)The effect of high-frequency ultrasound on doxorubicin (DOX) release from Pluronic micelles and intracellular DOX uptake was studied for promyelocytic leukemia HL-60 cells, ovarian carcinoma drug-sensitive and multidrug-resistant ... -
