Abstract:
A sonicator assembly, including: a microplate defining a plurality of wells; a manifold for containing a transducer fluid that is thermally coupled to the plurality of wells of the microplate; an ultrasonic generator operable for applying an ultrasonic excitation to the wells of the microplate; one or more of a heating module thermally coupled to and operable for selectively heating the transducer fluid and a cooling module thermally coupled to and operable for selectively cooling the transducer fluid; and a controller operable for controlling operation of the ultrasonic generator and the one or more of the heating module and the cooling module. The controller is further operable for monitoring a temperature and a pressure within the manifold. A temperature of the plurality of wells is controllable over a temperature range from 4° C. to 95° C. Optionally, the plurality of wells include a plurality of heat-resistant round-bottom hydrophilic wells.
Abstract:
Flow cytometry concepts are modified to enable dynamic characterizations of particles to be obtained using optical scattering data. Particles in flow will be introduced into a sample volume. Light scattered by a particle in the sample volume is collected and analyzed. What differentiates the concepts disclosed herein from conventional flow cytometry is the use of an acoustic source that is disposed to direct acoustic energy into the sample volume. As the particle passes through the sample volume, it responds to the acoustic energy, causing changes in the light scattered by the particle. Those changes, which are not measured during conventional flow cytometry, can be analyzed to determine additional physical properties of the particle.
Abstract:
A system for processing biological or other samples includes an array of transducer elements that are positioned to align with sample wells in a microplate. Each transducer element produces ultrasound energy that is focused towards a well of the microplate with sufficient acoustic pressure to cause inertial cavitation. In one embodiment, the transducers are configured to direct ultrasound energy into cylindrical wells. In other embodiments, the transducer elements are configured to direct ultrasound energy into non-cylindrical wells of a microplate.
Abstract:
Methods for treating an extravascular hematoma in a patient can include liquefying a first portion of the extravascular hematoma by applying a first series of focused acoustic pulses to the extravascular hematoma at a first frequency; and liquefying a second portion of the extravascular hematoma by applying a second series of focused acoustic pulses to the extravascular hematoma at a second frequency. Liquefied remains of the extravascular hematoma can be aspirated from the patient following liquefaction and disruption.
Abstract:
Cell-separation systems and methods utilizing cell-specific microbubble tags and ultrasound-based separation are described. The methods are useful for simplification of time-consuming and costly cell purification procedures and real time apoptosis detection.
