“…The inefficient mixing between reactants leads to loss of reaction products, which ultimately limits wide applications of marble‐based microreactors . Inspired by the powerful effect of electric force on liquid interfaces, which can deform droplets into conical shapes, induce the droplet coalescence, enhance the mixing of composite viscous liquid streams, we identify that this unique feature may provide an opportunity to achieve the efficient mixing between viscous reactants in marbles. Here, we apply an electric field to coalesce and mix multiple liquid marbles with viscous liquid interiors, such as glycerol.…”

Miniaturized droplet reactors hold great promise for the development of green and sustainable chemistry. However, handling liquids with small volumes, especially viscous ones, in a convenient and loss-free manner remains a challenge. Here, by electrically controlling the coalescence and mixing of particle-coated droplets, also known as liquid marbles, an effective micro reactor is demonstrated for miniaturized chemical reactions involving viscous reagents. By applying an electric voltage to marbles, the induced electromixing of marble microreactors promotes the reaction rate and the product yield. The advantages of electromixed marble reactors are manifested by a series of chemical reactions between aldehydes and 2-methylindole in viscous glycerol solution. The electrically-controlled coalescence and mixing establish liquid marbles as microreactors for rapid, efficient, and miniaturized chemical reactions.

“…Benefiting from their capability to separate liquid cargo and solid encapsulant as well as high cargo content, microcapsules have been widely applied in encapsulation, delivery, and release of actives in the fields of agriculture, cosmetics, drug delivery, detergents, and food additives [14][15][16][17][18]. A variety of techniques, such as spray drying, interfacial polymerization, complex coacervation, and microfluidics, have been employed for the preparation of functional microcapsules [19][20][21][22][23][24][25][26]. Among these methods, the microfluidics technologies can overcome limitations associated with variability during microcapsule production and generate functional microcapsules with fine-tuned chemical compositions, shell thicknesses, and encapsulant volume ratios by the precise control of their multiphasic flow [15][16][17][27][28][29][30][31][32] considerable challenges [16,33,34].…”
