Abstract: The present invention relates to an ethanol foam sclerosing agent for vascular anomalies and a preparation method thereof. The ethanol foam sclerosing agent includes absolute ethanol, water, Tween 80 and a stabilizer. The ethanol foam sclerosing agent further includes hyaluronic acid. The mass composition of the ethanol foam sclerosing agent includes 32-42% of absolute ethanol, 0.5-2% of Tween 80, 0-25% (excluding 0) of egg yolk lecithin, 0-2% (excluding 0) of hyaluronic acid, and the balance of water. The stabilizer is hyaluronic acid or glycerin. Foam is prepared by the Tessari method. While the original therapeutic effect of ethanol is not changed, the side effect of the ethanol is significantly reduced.

Abstract: The present application discloses an optoelectronic device, including an anode, a hole transport layer disposed on the anode, a quantum dot light-emitting layer disposed on the hole transport layer, and a cathode disposed on the quantum dot light-emitting layer; the quantum dot light-emitting layer includes a quantum dot material in a core-shell structure, and a difference between a top energy level of a valence band of an outer shell layer material of the quantum dot material and that of a hole transport material in the hole transport layer is greater than or equal to 0.5 eV.

Abstract: Systems and methods for a microfluidic biosensor patch and health monitoring system may include an iontophoresis module, a multi-inlet microfluidic sweat collection and sampling module, and a molecularly imprinted polymer (MIP) organic compound sensor module. An iontophoresis module may provide for stimulation of a biofluid sample. A biofluid may be a sweat sample. Stimulation may be achieved via electrostimulation and/or application of a stimulating agent. A microfluidic sweat collection and sample module may include several adhesive layers with carefully designed inlets, channels, a reservoir, and an outlet for the efficient collection and sampling of biofluid. A MIP sensor module may quickly and accurately identify concentrations of key metabolites present in a biofluid sample which may indicate certain health conditions.
