Abstract:
A method that modifies surface properties of a substrate by manipulating the immobilized biomolecules in mild biological condition. The manipulation comprised steps of: providing a biomolecule combined with at least one ssDNA combined with a first protein through an affinity binding tag; adding a second ssDNA conjugated with a second protein with a concentration greater than that of the first protein; and replacing the first protein on the ssDNA with the second protein through chemical competitive principle. The invention may comprise the steps with proper design of biotinylated DNA probes, the functionalized ssDNA nanotemplates can be recovered to its unbound state through a thermodynamic principle.
Abstract:
The present invention relates to a method for fabricating a thin film formed with a uniform single-size monolayer of spherical AZO nanoparticles. Because of its own advantages in cost and transparency, Al-doped ZnO (AZO) transparent conductive film is becoming the most commonly used transparent conducting oxide (TCO) replacement for solar cells. In this invention, a colloidal chemical means is adopted for enabling a chemical reaction between metal salts, water, and polyhydric alcohols at a room-temperature environment, and thereby, a process for fabricating spherical AZO nanoparticles in a diameter ranged between 100 nm to 400 nm according to different parameter configurations can be achieved while controlling the actual Al/Zn ratio to be ranged between 0.1% to 3%. In addition, a dip coating means is adopted for densely distributing the spherical AZO nanoparticles on a substrate into a monolayer close-packed structure.

A support structure for tablet display apparatus includes a support member and a connection assembly. The support member has a first end section and a second end section opposite to the first end section. The first end section is connected with the connection assembly via an angle adjustment seat, whereby the connection assembly can be rotated or tilted relative to the angle adjustment seat and located. The connection assembly is formed with a receiving space for receiving a tablet display apparatus. The second end section of the support member is pivotally connected with a base seat. Accordingly, the tablet display apparatus can be rotated and tilted by different angles and supported in an inclined position in adaptation to different situations and requirements.
