The present invention relates to the medical field, in particular to the treatment of neurological disorders. More specifically the present invention relates to a nanoparticle or nanoparticles' aggregate for use in prevention or treatment of a neurological disease or at least one symptom thereof in a subject without exposure of the nanoparticle or nanoparticles' aggregate to an electric field, and preferably without exposure thereof to any other external activation source, wherein the nanoparticle's or nanoparticles' aggregate's material is selected from a conductor material, a semiconductor material, an insulator material with a dielectric constant .sub.ijk equal to or above 200, and an insulator material with a dielectric constant .sub.ijk equal to or below 100. It further relates to compositions and kits comprising such nanoparticles and/or nanoparticles' aggregates as well as to uses thereof without exposure thereof to an electric field, and preferably without exposure thereof to any other external activation source.

The present disclosure provides a surface-modified alginate micro-capsule having a core-shell structure in which a core is fluidizable phase alginate, and a shell is alginate hydrogel crosslinked with epigallocatechin gallate dimer, a preparation method thereof, and a cell encapsulation method using the same.

Blood-brain barrier permeable peptide compositions that contain variable antigen binding domains from camelid and/or shark heavy-chain only single-domain antibodies are described. The variable antigen binding domains of the peptide compositions bind to therapeutic and diagnostic biomarkers in the central nervous system, such as the amyloid-beta peptide biomarker for Alzheimer's disease. The peptide compositions contain constant domains from human IgG, camelid IgG, and/or shark IgNAR. The peptide compositions include heavy-chain only single-domain antibodies and compositions with one or more variable antigen binding domain bound to one or more constant domains.

Provided herein are particles comprising a polymer substrate comprising one or more hyaluronic acid chains; and two or more peptide moieties bound directly to each hyaluronic acid chain. In some embodiments, the two or more peptide moieties comprising collagen-binding peptide (CBP) and von Willebrand binding peptide (VBP). The particles can be utilized in, e.g., methods of hemostatic treatment.

The invention provides microbubbles and/or nanodroplets labeled with diagnostic and/or therapeutic ligands that are useful in the detection and treatment of Alzheimer's disease, or related diseases and conditions, as well as methods of preparation and use thereof.

An apparatus, method, and use for ultrasound mediated microbubble delivery of pharmaceutical compositions to pulmonary tissue are provided. The pulmonary ultrasound apparatus includes an ultrasound signal generator for generating ultrasonic signals, an ultrasound transducer assembly having an ultrasound transducer operatively connected to the ultrasound signal generator, the ultrasound transducer configured to transmit the ultrasound signal generated by the ultrasound signal generator to pulmonary tissue, wherein the ultrasonic signal is transmitted at a frequency, a pressure, and a pulse duration for cavitating microbubbles to deliver a pharmaceutically active molecule to the pulmonary tissue.

A method for preparing a suspension of size-controlled gas-filled microvesicles by microfluidic manufacturing techniques, which comprises using a gaseous flow comprising a first gas having high solubility in water and a second gas having low 5 solubility in water.

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.

Novel siRNA and shRNA nanocapsules and delivery methods are disclosed herein. These siRNA and shRNA nanocapsules and delivery methods are highly robust and effective. This invention provides a platform for RNAi delivery with low toxicity and long intracellular half-life for practical therapeutic applications.

This invention relates to compositions, and related methods, of synthetic nanocarriers that comprise immunomodulatory agents and antigens that are differentially released from the synthetic nanocarriers.
