摘要:
There is provided an oral biofilm inhibitor having an exceptional inhibitory effect on oral biofilm formation. It is an oral biofilm inhibitor comprising a curable composition containing an antimicrobial agent, wherein a compressive strength of a cured product formed by curing the composition is 150 MPa or less, and a content of the antimicrobial agent is 0.001 to 3% by weight. An oral biofilm inhibitor thus obtained is used for inhibiting biofilm formation in an oral cavity by applying a curable composition containing an antimicrobial agent to a dental defect site for allowing the composition to cure at the dental defect site, and then disintegrating the cured composition.

The present invention relates to a rapid-setting hydraulic binder composition and, more specifically, to a hydraulic binder composition, which contains tricalcium aluminate (C3A) and dodecacalcium heptaaluminate (C12A7), and thus is rapidly set, has an easily adjustable setting time, and is bio-friendly.
摘要:
Provided herein are compositions for applying a reference marker pattern or grid to the surface of an object to be imaged three-dimensionally. These compositions can be quick drying for ease of use. Methods of use of the compositions are also provided as well as devices and kits for the application of the compositions.
摘要:
There is described a material comprising tapes, ribbons, fibrils or fibers characterized in that each of the ribbons, fibrils or fibers have an antiparallel arrangement of peptides in a β-sheet tape-like substructure wherein the material comprises a pair of self assembling complementary polypeptides.
