Abstract: The present application provides a microdroplet container and a method for manufacturing the same, a method for spreading microdroplets, a microdroplet-generating kit, a temperature-controlling device, an oil phase composition for microdroplet generating and a method for treating the same. The temperature controlling device includes a flexible circuit board a heating substrate, and multiple semiconductor electric couples. The semiconductor electric couples are disposed between the flexible circuit board and a first surface of the heating substrate, and are connected to each other.

Abstract: Disclosed is a liquid discharging nozzle, including a needle stem having a hollow chamber and an outlet end located at one end of the needle stem, an angle between a normal line of an end surface of the outlet end of the liquid discharging nozzle and an extension direction of the needle stem is equal to or smaller than 90°. Further disclosed are a motion controlling mechanism, a microdroplet generating device and method, a liquid driving mechanism and method, a microdroplet generating method, and a surface processing method of a liquid discharging nozzle.
