The interplay between academics and society within the environment of the COVID-19 pandemic has impacted on scientists across the world, prompting reevaluation of how virtual toolboxes can be used to support responsible collaborative research practices. We provide awareness of virtual resources and activities that enable scientific discovery using safe and efficient practices.

Quickly and easily producing uniform populations of microsphere-based 3D cell cultures using droplet-based templating methods has the potential to enable widespread use of such platforms in drug discovery or cancer research. Here, we advance the design of centrifuge-based droplet generation devices, describe the use of this platform for droplet generation with controlled cell occupancy, and demonstrate weeklong culture duration. Using simple-to-construct devices and easily implemented protocols, the initial concentration of encapsulated cells is adjustable up to hundreds of cells per microsphere. This work demonstrates the first instance of using centrifugal droplet-generating devices to produce large numbers of cell-encapsulating microspheres. Applications of this versatile methodology include the rapid formation of templated 3D cell culture populations suitable for suspension culture or large batch bioreactor studies that require uniform populations.

We present an easy-to-assemble microfluidic system for synthesizing cell-loaded dextran/alginate (DEX/ALG) hydrogel spheres using an aqueous two-phase system (ATPS) for templated fabrication of multicellular tumor spheroids (MTSs). An audio speaker driven by an amplified output of a waveform generator or smartphone provides acoustic modulation to drive the breakup of an ATPS into MTS template droplets within microcapillary fluidic devices. We apply extensions of Plateau–Rayleigh theory to help define the flow and frequency parameter space necessary for acoustofluidic ATPS droplet formation in these devices. This method provides a simple droplet microfluidic approach using off-the-shelf acoustic components for quickly initiating MTSs and subsequent 3D cell culture.
