Despite their potential, working with droplets at the nanoscale presents several challenges:
Size Control: Achieving and maintaining uniform droplet size can be difficult but is essential for consistent results. Stability: Droplets can be unstable and susceptible to coalescence or evaporation, which can affect their functionality. Manipulation: Precise control over droplet movement and positioning is necessary but can be technically challenging. Material Compatibility: Ensuring compatibility between the droplets and their environment or substrates to prevent unwanted reactions or degradations.
