摘要:
The invention provides novel apparatus and methods for efficiently and accurately filling vials with gaseous materials such as a fluorinated gas, with or without concomitantly filling the vials with another liquid or solid material.
摘要:
Phase change nanodroplet conjugates and methods of making and using thereof are provided. The phase change nanodroplet conjugates include a nanodroplet having a gaseous precursor on the interior and an outer shell such as a lipid monolayer, a lipid bilayer, or a polymer layer. The phase change nanodroplet conjugates can have one or more nanoparticles attached to the outer layer, e.g. via a linker. The nanoparticles can include therapeutic, prophylactic, or diagnostic nanoparticles. The phase change nanodroplet conjugates can be used for the targeted delivery of a therapeutic, prophylactic, or diagnostic nanoparticle to a target region in a subject in need thereof. The methods can include applying an effective amount of ultrasound radiation to the target region to stimulate vaporization of the gaseous precursor followed by cavitation of the resultant bubble conjugate and release or dispersing of drug or drugs inside the liposomes. Methods of making phase change nanodroplet conjugates are also provided.
摘要:
A photoacoustic apparatus is used that has: a detecting unit that detects photoacoustic waves generated by an object containing contrast agent in first blood vessels of circulating blood and in second blood vessels; and a signal processing unit that generates contrast agent distribution and acquires contrast agent concentration change in the circulating blood. The signal processing unit acquires the position of the first blood vessels on the basis of a time-series change of the contrast agent distribution and the contrast agent concentration change, and lowers the concentration at the position of the first blood vessels on the basis of the contrast agent distribution.
摘要:
The present invention relates to a method of preparation of ultrasound contrast agent precursors comprising phospholipid- stabilised perfluorobutane microbubbles. The method is amenable to commercial scale manufacture, and provides more consistent vial-to-vial yields and size distribution of said microbubbles. Also provided are methods of preparing kits and ultrasound contrast agents using the method of the invention.
摘要:
Embodiments associated with an ultrasound conductive medium are described. In one embodiment, an ultrasound conductive substance (500) is formed into a solidified shape and includes a locking element (505) for connecting to a device.
摘要:
There is provided herein a nanovesicle having a bilayer comprising a saturated first phospholipid and no more than about 15 molar % of a second phospholipid covalently conjugated to a J-aggregate forming dye.
摘要:
This invention relates to bubble generation, in particular to microbubble generation in a microfluidic device, which bubbles may be useful as contrasting agents or drug delivery vehicles. The invention further relates to apparatuses, systemsand methods for manufacturing said microbubbles, microbubbles produced by such methods and to their uses, e.g. in medical, diagnostic and other such applications. The microbubbles are preferentially formed using a microspray regime.
摘要:
A method and system are provided for detection of localized hydrogen peroxide within tissue by introducing a catalase-containing material into at location of interest, positioning an ultrasound transducer over the location, and generating an ultrasound image to detect microbubbles, where the presence of microbubbles indicate the presence of localized hydrogen peroxide. The catalase-coated surface may be the inner surface of a microtube, on the surface of or incorporated within a nanosphere or microsphere, or an implantable device.
