Abstract: The present invention relates to an assembly and a corresponding method for performing a combined assay of nucleic acid purification and amplification from a biological sample, in particular with regard to prepare a library for next generation sequencing. A unique rotary design of one or more fluidic cards in the assembly allows for moving of biological samples and reagents around the fluidic card(s) based on centrifugal force provided by rotary motion and coupled with an indexing mechanism. By orienting the fluidic card(s) appropriately the fluidic flow can be directed from and to the various chambers on the fluidic card(s) to perform the different assay steps without the need of batching during sample processing.

Abstract: The present application discloses a waterproof smart watch having a hollow watch case; a cell phone core mounted inside the watch case; a through-hole provided on a lateral side of the watch case and in communication with a microphone of the cell phone core; an adjusting knob rotatably mounted at the lateral side of the watch case, a communication aperture being provided on the adjusting knob and in communication with the through-hole; and a sealing pad being provided between the adjusting knob and the watch case, a small hole being provided on the sealing pad and in communication with the through-hole. The adjusting knob can be rotated to a position where the communication aperture, small hole and through-hole are in communication with one another successively, and further rotation of the adjusting knob renders the communication aperture and the through-hole being sealed and separated by the sealing pad.
