The present disclosure relates to the field of digital microfluidics, and provides a microfluidic particle comprising a charged droplet, an intermediate cladding layer, and a dielectric surface layer. The intermediate cladding layer is hydrophobic and coated outside the charged liquid droplet. The dielectric surface layer is hydrophilic and is coated outside the intermediate cladding layer. A microfluidic system is also provided, where the microfluidic system comprises a digital microfluidic chip and the microfluidic particle is disposed above the digital microfluidic chip.
