Digital Liquid Patterning: A Versatile Method for Maskless Generation of Liquid Patterns and Gradients

Alexander N. EfremovMichael GrunzePavel A. Levkin

A facile, maskless, digital liquid patterning method, allowing on-demand fabrication of liquid patterns without the need to change the substrate or use different photomasks, is described. Patterns with customized geometries can be created manually by simple pipetting. An application of this maskless method to create patterns of particles, cells, hydrogels, and complex liquid gradients compatible with cell studies is shown.

Inscribing Wettability Gradients Onto Superhydrophobic Carbon Nanotube Surfaces

Tunable wettability of carbon nanotube (CNT) arrays on the nanoscale is the key to move water droplets on such surfaces on a macroscopic scale. A novel type of superhydrophobic CNT surface for guided droplet transport, a key issue for future microfluidic systems, is demonstrated. It is accomplished by tailoring the required surface roughness using a process employing CNT regrowth, chemical passivation, and corona discharge.

Three-Dimensional Graphene Composite Macroscopic Structures for Capture of Cancer Cells

A hierarchical nanostructured 3D platform is reported that combines microporosity with a nanostructure for selective capture of cancer cells. The microporosity allows red blood cells to travel through, while the anti-EpCAM modified nanostructure captures circulating tumor cells. These systems allow for considerable increase in the contact frequency between target cells and the substrate, thus enhancing the cancer cell filtration and isolation efficiency.
