Nanocrystals, compositions, and methods that aid particle transport in mucus are provided. In some embodiments, the compositions and methods involve making mucus-penetrating particles (MPP) without any polymeric carriers, or with minimal use of polymeric carriers. The compositions and methods may include, in some embodiments, modifying the surface coatings of particles formed of pharmaceutical agents that have a low water solubility. Such methods and compositions can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for administration routes involving the particles passing through a mucosal barrier.

Provided herein is a pharmaceutical composition comprising an effective amount of cypate-Cyclo(Cys-Gly-Arg-Asp-Ser-Pro-Cys)-Lys-OH (LS301), cypate-Cyclo(Cys-Gly-Arg-Asp-Ser-Pro-Cys)-Tyr-OH (LS838) or pharmaceutically acceptable salts thereof, wherein each amino acid residue is independently in a D or L configuration; a divalent metal ion; and a pharmaceutically acceptable carrier. Further provided are lyophilized products comprising a dye-conjugate and m methods for identifying compromised and for binding phosphorylated annexin A2 (pANXA2) protein in a biological sample using a composition described herein.

A device and method for staining the eye of a patient in need of the same includes the introduction, onto the surface of the eye, of a dry powder form at a dye suitable for staining the eye. The dry powder form of the dye is introduced onto the surface of the eye without the use of a substrate at or near the eye's surface.
