The present invention relates to silica hollow nanoparticles having inside their cavity a metal core consisting of inorganic nanostructures coated by a protective agent and agglomerated with a polymeric aggregating agent, useful in particular in medicine in the bio-imaging techniques and/or in the radio-therapeutic or chemo-therapeutic techniques; the invention moreover refers to a process for the preparation of such nanoparticles.

The present invention relates to compositions and methods for treating diseases and disorders including cancer and various other angiogenic-dependent diseases, vascular malfunctions, arteriovenous malformations (AVM), hemorrhagic processes and treatment of pain, in particular tumor-related pain by drug delivery and/or therapeutic embolization using microspheres. More particularly the invention relates to microspheres containing non-ionic contrast agents, to compositions comprising these microspheres, as well as methods for preparing and using such compositions for embolization therapy. The invention further relates to compositions and methods using detectable microspheres for targeted drug delivery, irrespective of whether embolization is also needed.

The present invention relates to novel amphiphilic dendrimers, hereafter denoted Dendri-TAC. The present invention also relates to perfluorocarbon nanoemulsions stabilized by these amphiphilic dendrimers and their uses for in vivo diagnostic and/or for therapy, notably as theranostic tools, for detection and/or treatment of cancer.

The present invention is directed to compositions useful in assembling vesicles. The composition comprises a first block copolymer; a plurality of first inorganic nanoparticles; a second block copolymer; and a plurality of second inorganic nanoparticles or a plurality of small molecules. The composition is characterized by the ability to self-assemble into a vesicle. Also provided is a method of making a composition for delivery of a therapeutic agent and a method of using the vesicles as imaging agents.

The invention relates to probiotic bacteria selected from lactic acid bacteria, such as Lactobacillus and Bifidobacteria, having metals and/or metal nanoparticles and to foodstuff and pharmaceutical composition having these bacteria. The invention also provides methods for obtaining these bacteria and uses of these bacteria for the treatment and prevention of mineral deficiency pathologies, as a contrast agent for the imaging of the digestive tract and for the treatment of cancer.

Disclosed are methods for designing and manufacturing biomimetic proteolipid nanovesicles using a microfluidic approach, and in particular, a NanoAssemblr-based platform, which allows for the high-throughput, reproducible, and scalable production of nanoparticles, without affecting their pharmaceutical and biological properties. These nanovesicles, which are composed of synthetic phospholipids and cholesterol, enriched of leukocyte membranes, and surrounding an aqueous core, possess remarkable properties for targeting compounds of interest to particular mammalian cell and tissue types.

Described herein are formulations that can include one or more enzymes that can break down one or more components of scar tissue. Also provided herein are methods of treating scar tissue by administering a formulation provided herein to a subject in need thereof.

Radiopaque monomers, polymers, and microspheres are disclosed herein. Methods of using the radiopaque monomers, polymers, and microspheres are disclosed herein. Methods of manufacturing radiopaque monomers, polymers, and microspheres are disclosed herein.

The present invention provides novel compositions of binding moiety-nanoparticle conjugates, aggregates of these conjugates, and novel methods of using these conjugates, and aggregates. The nanoparticles in these conjugates can be magnetic metal oxides, either monodisperse or polydisperse. Binding moieties can be, e.g., oligonucleotides, polypeptides, or polysaccharides. Oligonucleotide sequences are linked to either non-polymer surface functionalized metal oxides or with functionalized polymers associated with the metal oxides. The novel compositions can be used in assays for detecting target molecules, such as nucleic acids and proteins, in vitro or as magnetic resonance (MR) contrast agents to detect target molecules in living organisms.

This invention provides methods and systems for achieving high-specificity killing of targeted cells using Magneto-Electric Nano-Particles (MENPs) and functional or diagnostic imaging that detects changes at the cellular level. Embodiments comprise injecting into a patient's body manufactured MENPs that have a higher tendency to accumulate near or attach to targeted cells through one or more physical forces and/or biological mechanisms; and applying a magnetic field to the MENPs to generate an action that is sufficient to cause death of the targeted cells, and using an imaging apparatus to image or detect a specific property of the MENPs or changes in a property of the MENPs due to the coupling of the MENPs with their surrounding environment.
