Claims10
A microcontainer microstructure comprising:
- a substrate provided with a hole having an upper opening and a lower opening;
- and
- a microcontainer film structure formed in contact with an inner surface of the hole and comprising a container portion having a volume of 100um3 to 1,000,000 um3 and a sharp tip portion,
- wherein the container portion is loaded with a drug,
- wherein the container portion and the sharp tip portion of the microcontainer film structure are both configured to be inserted into a human body, and
- wherein the substrate is configured to contact a surface of the human body but not be inserted into the human body.
