New hot articles on cargo-lifting for microfluidics, mimicking cell environments and ‘fluidic batteries’

C2LC21301J graphical abstractGabriel Loget and Alexander Kuhn report for the first time the vertical propulsion of conducting beads in liquid filled capillaries by bipolar electrochemistry. Using a conical capillary a Yo-Yo type motion can be induced, making the concept then useful for cargo-lifting and of potential interest for microfluidic applications in lab-on-a-chip devices.

C2LC21117C graphical abstractPhilip LeDuc and colleagues from Carnegie Mellon University report the development of a minimal-profile, three-dimensional (MP3D) experimental microdevice which confines cells to a single focal plane, allowing observation with conventional epifluorescent microscopy.

C2LC40126F graphical abstract

Scott Phillips and colleagues at Pennsylvania State University describe the first paper-based microfluidic device that is capable of generating its own power when a sample is added to the device. The microfluidic device contains galvanic cells (“fluidic batteries”) integrated directly into the microfluidic channels.
