Ultrasound-Induced Calcein Release From eLiposomes
(Elsevier, 2012)
Ultrasound is explored as a method of inducing the release of encapsulated materials from eLiposomes, defined as liposomes containing emulsion droplets. Emulsions were formed using perfluorohexane and perfluoropentane. ...
Non-Viral Gene Transfection with Ultrasound: Is 100% Transfection Possible?
(American Scientific Publishers, 2012)
Ultrasound has been used as a modality to enhance the transfection of cells, purportedly via entry of genetic material through defects in the cell membrane produced by bubble cavitation events. A mathematical model was ...
Kinetics and thermodynamics of acoustic release of doxorubicin from non-stabilized polymeric micelles
(Elsevier, 2010)
This paper studies the thermodynamic characteristics of ultrasound-activated release of Doxorubicin (Dox) from micelles. The release and re-encapsulation of Dox into Pluronic® P105 micelles was measured by recording the ...
Phase transitions of perfluorocarbon nanoemulsion induced with ultrasound: A mathematical model
(Elsevier, 2013)
While ultrasound has been used in many medical and industrial applications, only recently has research been done on phase transformations induced by ultrasound. This paper presents a numerical model and the predicted results ...
Optimizing the use of ultrasound to deliver chemotherapeutic agents to cancer cells from polymeric micelles
(Elsevier, 2011)
In this study, we present an artificial neural network (ANN) model that attempts to predict the dynamic release of doxorubicin (Dox) from P105 micelles under different ultrasonic power densities at 20 kHz. The goal is to ...
Investigating the Stability of eLiposomes at Elevated Temperatures
(Sage Publishing, 2014)
eLiposomes encapsulate a perfluorocarbon nanoemulsion droplet inside a liposome. Ultrasound is then used as a trigger mechanism to vaporize the perfluorocarbon, break the liposome, and release the desired drug to the tumor ...
Distribution of Doxorubicin in Rats Undergoing Ultrasonic Drug Delivery
(Elsevier, 2010)
Ultrasound (US) increases efficacy of drugs delivered from micelles, but the pharmacokinetics have not been studied previously. In this study, US was used to deliver doxorubicin (Dox) sequestered in micelles in an in vivo ...
Kinetics of acoustic release of doxorubicin from stabilized and unstabilized micelles and the effect of temperature
(Elsevier, 2011)
Ultrasound is being investigated as a trigger mechanism to deliver high concentrations of chemotherapy drugs to cancerous tissues using polymeric micelles. In this paper, we examined the kinetics of acoustic release of ...
Phase transitions of nanoemulsions using ultrasound: Experimental observations
(Elsevier, 2012)
The ultrasound-induced transformation of perfluorocarbon liquids to gases is of interest in the area of drug and gene delivery. In this study, three independent parameters (temperature, size, and perfluorocarbon species) ...
Mathematical modeling of microbubble cavitation at 70 kHz and the importance of the subharmonic in drug delivery from micelles
(Elsevier, 2013)
In order to gain insight into the experimental observation of ultrasound-induced release of drugs from micelles, we modeled the dynamic oscillations of a 10-μm-diameter bubble insonated at 70 kHz. The Parlitz modification ...
