Compositions that include nanoscale structured materials or precursors thereof (e.g., self: assembling peptides) are described. The compositions can include other substances (e.g., a vasoconstrictor). Also described are methods for using the compositions to promote hemostasis, to protect the skin or wounds from contamination, to decontaiminate a site upon removal of previously applied compositions that provided a protective coating, and to inhibit the movement of bodily substances other than blood. The compositions are also useful in isolating tissue, removing tissue, preserving tissue (for, e.g., subsequent transplantation or reattachment), and as bulking, stabilizing or hydrating agents. Medical devices that include the compositions (e.g., a stent or catheter), bandages or other wound dressings, sutures, and kits that include the compositions are also described.

Compositions and methods for promoting hemostasis and other physiological activities

Compositions which self-assemble under physiological conditions are formulated for application to wounds. The formulations include a pharmaceutically acceptable carrier or are provided as part of a medical device or coating. The formulations may also include other therapeutic, prophylactic or diagnostic agents. The formulation can be administered for treatment of one or more disorders or conditions. For example, the formulation may be applied to repair an injury or during surgery of the lung, eye or dura, or following an epidural or spinal tap, to stop leakage of blood, interstitial fluid, or cerebrospinal fluid. The formulation may be administered to a burn or ulcer. In one embodiment, the formulation is provided as a dry or lyophilized powder. In another embodiment, the material is provided in water. In another embodiment, the material is provided in combination with an oil and forms a laminate.

Compositions and methods for affecting movement of contaminants, bodily fluids or other entities, and/or affecting other physiological conditions

Method are described for inhibiting movement of a bodily fluid and/or contaminants on or in an animal comprising administering to the animal self-assembling peptidomimetics, including &#x3b1;-peptides, &#x3b2;-peptides, &#x3b3;-peptides, and/or &#x3b4;-peptides.

Compositions which self-assemble under physiological conditions are formulated for application to wounds. The formulations include a pharmaceutically acceptable carrier or are provided as part of a medical device or coating. The formulations may also include other therapeutic, prophylactic or diagnostic agents. The formulation can be administered as appropriate for treatment of one or more disorders or conditions. For example, the formulation may be applied to repair an injury or during surgery of the lung, eye or dura, or following an epidural or spinal tap, to stop leakage of blood, interstitial fluid, or cerebrospinal fluid.

This invention provides a method for treating an eye disease in a patient comprising: providing a photosensitive prodrug that releases upon exposure to light an active ingredient to treat the eye disease; administering the prodrug in a pharmaceutically accepted vehicle to the subject, and exposing the eye of the subject to an external light source to cause the prodrug to release the active ingredient. This invention also provides a composition for the treatment of glaucoma, comprising a compound containing a lithium ion-chelated in a crown ether- or aza-crown ether-containing chromene or diazene derivative and a pharmaceutically acceptable carrier.
