The development of non-toxic quantum dots and further investigation of their composition-dependent cytotoxicity in a high-throughput manner have been critical challenges for biomedical imaging and gene delivery. Herein, we report a rapid sonochemical synthetic methodology for generating a library of highly biocompatible ZnS-AgInS(2) (ZAIS) quantum dots for cellular imaging and siRNA delivery.

A novel application of surface-modified protein nanospheres as potential antiviral agents is illustrated. By using a single-step sonochemical process, bovine serum albumin nanospheres were generated, whose surface was covalently conjugated with mercaptoethane sulfonate to chemically and electrostatically mimic cellular heparan sulfate. The nanospheres effectively inhibited HSV-1 infection.

A novel high-frequency, high-power, pilot-plant scale sonochemical reactor was developed and used to study the degradation of dichloromethane, trichloroethylene, phenol, and methyl orange in aqueous solutions. The degradation rates of trichloroethylene, dichloromethane, and phenol were found to exceed those of similar frequency, small-scale bench reactors by factors ranging from 2.5 to 7. The d...

High intensity ultrasound has been applied to two classes of step-growth polymerisation. The ring-opening polymerisation of cyclic lactones to polyesters was accelerated under 20 kHz ultrasound but, in the case of delta-valerolactone, sonication also promoted a depolymerisation reaction so that the molecular weight fell during later stages of the reaction. Sonication was also applied to the pre...

Describes the ability a managing the symmetric sonochemical reactor for physic-chemical treatment of chemically pure water, true and colloidal aqueous solutions, as well as disperse systems with the speed of sound in them more than at water. Such reactors are useful, for example, in the food industry, where are processed of different concentrations the solutions NaCl. Demonstrated that the deve...

In the present study, ZnO nanostructure has been synthesized by different methods, namely coprecipitation, hydrothermal and sonochemical methods. After comparison of the morphology and photocatalytic activity of ZnO samples prepared via different methods, the best method (sonochemical method) was used for synthesis of Ni-ZnO nanoparticles with different concentrations of nickel. Furthermore, st...

Sphere-like cadmium molybdate (CdMoO4) nanostructures have been synthesized by a large scale and simple sonochemical method by using Cd(Sal)2 (Sal=salicylidene) and Na2MoO4.2H2O for the first time. The effects of sonochemical irradiation time, sonochemical power, temperature, solvent, surfactant and cadmium source were considered to obtain a controlled shape. The as-prepared nanostructured cadm...
