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 ... -
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 ... -
Factors affecting acoustically triggered release of drugs from polymeric micelles

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 ... -
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 ... -
Alkyl Monolayers on Silica Surfaces Prepared from Neat, Heated ClSi(CH₃)₂(CH₂)₆CH=CH₂ Analyzed by XPS
(American Vacuum Society, 2002)Silane monolayers on silica, prepared from mono-, di-, and trichlorosilanes, are widely used in industry for surface functionalization and modification. However, unlike di-and trichlorosilanes, monochlorosilanes are ... -
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 ... -
