Microfluidic platform and method for controlling the same

A microfluidic platform, comprising:

• a microfluidic layer embedded with a microfluidic structure, the microfluidic structure comprising a micro-channel and a fluidic sample contained in the micro-channel;
• and
• a contact layer attachable to the microfluidic layer, comprising a first heater for heating a first area of the microfluidic structure to a first temperature and a second heater for heating a second area of the microfluidic structure to a second temperature,
• wherein the microfluidic layer and the contact layer rotate together during operation, the microfluidic structure is shaped such that the sample is under a centrifugal force when the microfluidic layer rotates, and the micro-channel is filled with oil and the sample is an aqueous droplet.
