Abstract

Front Cover: The cover image is based on the Research Article Digital twin of a droplet microarray platform: Evaporation behavior for multiple droplets on patterned chips for cell culture by Wu et al.

This cover highlights evaporation phenomenon of multiple droplets on patterned surfaces, affected by humidity, temperature, and droplet distribution. We establish a digital twin system and propose a theoretical method to detect volumes and pH variation on evaporating droplets onto patterned substrates. The proposed strategy allows us to achieve an active maneuver of the collective evaporation of droplets on patterned surfaces. (DOI: 10.1002/dro2.94)
