Acoustically-levitated drop reactor (ldr) employable for kinetics measurements of biochemical networks
… the prevention of chemical contamination between drops and external objects, rapid mixing within the drop as a result of circulation driven by the levitating ultrasound, and freedom from wall interactions. We have developed an Acoustically-Levitated Drop Reactor (LDR) to study enzyme-catalyzed …

Effect of geometric parameters on drop-positioning forces for a levitated drop reactor
… plate and reflector of a single-axis acoustic drop levitator, in order to better understand the dependence of levitation capability on geometric parameters. Modifications to the drop levitator radiating plate are investigated using the BEM. Gor’kov’s theory is used to calculate the acoustic …

Developments in Analytical Chemistry: Acoustically Levitated Drop Reactors for Enzyme Reaction Kinetics and Single-Walled Carbon Nanotube-Based Sensors for Detection of Toxic Organic Phosphonates
… chemistry were made using acoustically levitated small volumes of liquid to study enzyme reaction kinetics and by detecting volatile organic compounds in the gas phase using single-walled carbon nanotubes. Experience gained in engineering, electronics, automation, and software …

Towards electrochemical diagnostics of biochemical free radical species in aqueous microliter volumes
… reactant consumption must be minimized. Levitated drops show potential as microreactors where radicals are present as reactants or products. Solid/liquid interfaces are absent or minimized, avoiding adsorption and interfacial reaction of conventional microfluidics. Probing small volumes …

Numerical study of the nonlinear dynamics of the acoustic drops and bubbles
The dynamics of liquid drops and bubbles held together by surface tension and perturbed by small disturbances is of great interest to many researchers. Its essential physical nature is characterized by a nonlinear moving-boundary problem complicated by the interfacial stress interaction between two …
