This application relates to a magnetically actuatable functional microscaffold for efficient targeted therapy of intractable diseases and a preparation method thereof. The magnetically actuatable functional microscaffold and the preparation method can enable the application of magnetic nanoparticles according to the status of the scaffold and enable various types of targeted therapy in the field of targeted therapy of intractable diseases.

Antimicrobial micro- or nanoparticles comprising a chlorhexidine salt and an anion, and a method of making the antimicrobial micro- or nanoparticle, are disclosed. The anion in the salt is selected form oxoanions and partially hydrogenated oxoanions of phosphorus, carbon, nitrogen, and sulfur.

The present disclosure relates to multilayer coatings that include a hydrophobic encasing layer and allow controlled release of a water soluble drug. The encasing layer encases water soluble, or hydrophilic, drugs with a flexible layer and comes in good intimate contact with the water soluble drug layer. Thus, the encasing layer conforms to the water soluble drug and can control the release of the drug. Advantageously, major cuts or fissures in the coating do not cause the water soluble drug to leak or burst out; rather, the encasing layer continues to provide modulated release of the drug. The present disclosure also includes methods of making the multilayer coatings, methods of using the multilayer coatings, and articles that include the multilayer coatings.

A drainage bag is provided for a thermal control unit adapted to deliver temperature-controlled liquid to a patient in order to control the patient's temperature. The drainage bag is used to hold and transport the liquid when the liquid inside the thermal control unit is changed. The drainage bag includes a bottom layer, a top layer sealed thereto, and a float secured to the top layer that is positioned adjacent an opening in the top layer. As the liquid from the thermal control unit drains into the opening in the top layer, the liquid lifts the float and the float lifts the top layer of the bag. The bag thereby expands its volume to accommodate the liquid from the thermal control unit. The bag may further be designed to be carried without sealing the opening and without spilling the liquid. A method for using the bag is also disclosed.
