Abstract
An apparatus for drug delivery is presented in accordance with aspects of the present disclosure. The apparatus includes a laser-driven photoacoustic microfluid pump (LDMP), an open tube capillary including a first end and a second end; the first end disposed on the LDMP, the open tube capillary configured to store a drug. The LDMP is configured to generate a fluidic jet from the drug and deliver the drug.
Claims4
A method for manipulating a cell, comprising:
- grasping a cell by using a fluid tweezer, the fluid tweezer including:
- a two directional laser-driven photoacoustic microfluid pump (LDMP) including an optical fiber light bending unit including a first end and a second end;
- thermally expanding and contracting a layer of photoacoustic material disposed on the second end of the optical fiber in response to the laser beam striking the layer of photoacoustic material;
- and generating two directional fluidic jets in a medium.
