Provided are a superabsorbent polymer capable of exhibiting improved bacterial growth-inhibitory property without deterioration in physical properties of the superabsorbent polymer, such as water retention capacity and absorbency under pressure, or without an increase in the generation of dust, and a preparation method thereof. The superabsorbent polymer may include a base polymer powder including a crosslinked polymer of water-soluble ethylenically unsaturated monomers including acidic groups, of which at least a part is neutralized; and a surface-crosslinked layer which is obtained by additionally crosslinking the crosslinked polymer via a surface crosslinking agent to be formed on the surface of the base polymer powder, wherein the crosslinked polymer of the base polymer powder or the surface-crosslinked layer includes an antimicrobial agent including an organic acid salt having an aromatic ring inside the crosslinked structure thereof.

Biodegradable, cross-linked polymer particle embolics and methods of making the same are described. The particle embolics can be used as embolization agents.

Disclosed herein are compositions that can form a covering, layer, film, device, and/or prosthetic skin that can be comfortably worn to provide skin barrier function, skin hydration and therapeutic and aesthetic benefits. The present invention provides novel compositions that have low tackiness and form quickly, resulting in a wearable, comfortable (maintains temperature and humidity), breathable, thin, optically invisible, cosmetically elegant, flexible, stretchable, elastic and body-movement conforming, yet long-lasting covering, layer, film, device, and/or prosthetic skin on the skin or any other body surface. The present invention provides novel compositions that can form a covering, layer, film, device, and/or prosthetic skin that works for extended periods in excess of about 24 hours, while retaining function during and after exercising, showering and swimming (in sea-water, fresh water and chlorinated water), steam room (heat at high humidity), and sauna (heat at low humidity).

Biodegradable, cross-linked polymer particle embolics and methods of making the same are described. The particle embolics can be used as embolization agents.

Described herein are magnetic adhesive compositions. The adhesive compositions can comprise a curable matrix comprising one or more reactive precursor molecules, and a population of magnetic particles dispersed within the curable matrix. The magnetic particles can each comprise a magnetic particle core and shell at least partially encapsulating the magnetic particle core. The magnetic particles can be present in an effective amount to induce and direct flow of the adhesive composition under an applied magnetic field. As a consequence, a magnetic field can be used to control application and/or curing of these adhesive composition at a desired location. For example, these adhesive compositions can be applied as a flowable fluid, and subsequently directed to flow to a desired location prior to curing (and/or held at a desired location during curing). Accordingly, also provided are methods of adhering surfaces using these adhesive compositions.

Described are polymers and methods of forming and using same.

An aerogel wound dressing including one or more aerogel layers, including a sensing component for monitoring a wound environment, and methods for treating a wound using an aerogel wound dressing. The wound dressing includes a base layer including which may include a sensing component, and optional removable layers which may be removed upon saturation of a wound exudate when used to treat a wound. The methods for treating a wound include applying an aerogel wound dressing to a wound, monitoring for infection, replacing the wound dressing upon infection, and replacing the removable layers upon saturation of wound exudate.

The present disclosure relates, in part, to cross-linked telechelic polymer compositions and methods of preparation thereof. In another aspect, the present disclosure relates to multilayer compositions comprising an adhesive base (AB) and a mechanically reinforcing composition (MRC), methods of preparation thereof, and methods of use thereof. In certain embodiments, the in situ prepared compositions are suitable for application to the skin of a subject for treating a wound and/or skin condition.
