Disclosed herein is a nanocomposite comprising a core-shell nanoparticle and a core-shell quantum dot. The core-shell nanoparticle comprises a phosphor core, a shell layer, and a cleavable peptide. The core-shell quantum dot comprises a center core, an intermediate layer, an outer layer, a silica layer, and an arginylglycylaspartic acid (RGD) peptide. The core-shell nanoparticle and the core-shell quantum dot are linked to each other via forming a peptide bond between the cleavable peptide and the RGD peptide. Also disclosed are the uses of the nanocomposite in making a diagnosis of tumors.

Nanocomposite and uses thereof

Disclosed herein is a micro-reactor for synthesizing a molecule, for example, compound, a nanoparticle, or a quantum dot. According to embodiments of the present disclosure, the apparatus comprises a processor, a storage unit, a reaction unit, a detector, and a collector, in which the storage unit and the reaction unit are independently controlled by the process. Optionally, the present micro-reactor further comprises a diagnostic device for performing a diagnostic test on a biological sample by use of the molecule. Also disclosed wherein are methods of diagnosing and treating a disease in a subject with the aid of the present micro-reactor.

Micro-reactor and method of use

A structure of an ink-jet printer head of a piezoelectric type comprising a deformable polymer membrane, an actuator and an ink tank is provided. The deformable polymer membrane covers the top opening of the ink tank to enclose the ink tank. The actuator, which is a double-layer piezoelectric ceramic plate, is mounted on the deformable polymer membrane with one end thereof being fixedly connected to the polymer membrane and the other end thereof being free to vibrate. As a double-layer piezoelectric ceramic plate is employed as the actuator, it includes a top and a bottom piezoelectric layers. A predetermined voltage signal is applied selectively across the upper-surface electrode and the lower-surface electrode of the top and bottom piezoelectric layer respectively such that the top piezoelectric layer extends and the bottom layer shortens selectively. The different directions of the deformation of the top and bottom piezoelectric layers, therefore, cause the desired vibration of the free end of the actuator. The vibration action of the deformable membrane causes a perturbation action to the ink inside the tank such that the ink is jetted, through the outlet, towards the outside of the printer head.
