Abstract: The present disclosure relates to a contact lens for drug delivery with improved drug delivery efficiency and bioavailability. Since the contact lens for drug delivery according to the present disclosure is capable of stably releasing a drug, compared to ophthalmic solutions in the art, bioavailability may be expected to be enhanced by reducing the dosage and frequency of administration. In addition, the contact lens for drug delivery according to the present disclosure may be easily applied to various drugs, has little irritation to the ocular mucosa, and is useful for mass production because of its easy preparation method.

Abstract: According to an embodiment, a contact lens includes: a vision correction lens portion positioned in a center portion of the contact lens to refract light; and a plurality of tear storage structures radially arranged from the center portion of the contact lens to store tears, wherein each of the plurality of tear storage structures includes a concave structure formed in the contact lens and having a first depth to store introduced tears. According to an embodiment, a contact lens includes: a vision correction lens portion positioned in a center portion of the contact lens to refract light; and a drug storage structure arranged apart from the center portion and configured to store a drug, wherein the drug is provided to an eye of a user wearing the contact lens.

Abstract: The present invention relates to an apparatus for single cell trap and position fixing of the trapped cell thereof, and specifically, it induces cell movement from where fluid flows strongly to where the fluid flows weakly, by injecting pressed air to an air channel to modify a thin film of a vibrator, and therefore to induce the fluid flow. Further, the present invention relates to an apparatus which can fix the cell position as well as minimizing the external stimulation to the cells, wherein single cells are trapped in a region wherein the fluid flows are minimized and their positions are fixed using the effect that the fluid flows induced by the vibrators are offset one another because the vibrators are formed symmetrically one another.
