Scientists have developed a method to create microfluidic platforms by using 3D printing to pattern hydrophobic barriers within hydrophilic filter paper, which can effectively guide liquid flow for applications like mixing and two-phase separation. According to Phys.org, this innovative approach demonstrates the potential for precise liquid manipulation in miniaturized systems.
