Embodiments of the present disclosure relate to materials and methods for preparing a clathrate-forming composition comprising a plurality of linear glucomonomer chains of about 15 to about 100 D-glucopyranosyl residues linked by ?-1,4 linkages, wherein the linear glucomonomer chains are a product of partial amylolysis of a modified starch substrate and wherein the product is flowable at temperatures within a range of 4-20? C. at about 20% w/v solids content. The present disclosure further describes methods of using the clathrate-forming compositions to form molecular dispersions or clathrates with hydrophobic guest molecules, kits for use in these methods, and molecular dispersions or clathrates obtained from the materials.

A modified starch material for biocompatible hemostasis, biocompatible adhesion prevention, tissue healing promotion, absorbable surgical wound sealing and tissue bonding, when applied as a biocompatible modified starch to the tissue of animals. The modified starch material produces hemostasis, reduces bleeding of the wound, extravasation of blood and tissue exudation, preserves the wound surface or the wound in relative wetness or dryness, inhibits the growth of bacteria and inflammatory response, minimizes tissue inflammation, and relieves patient pain. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. After treatment of surgical wounds, combat wounds, trauma and emergency wounds, the modified starch hemostatic material is rapidly absorbed by the body without the complications associated with gauze and bandage removal.
