“…This reaction enhancement has been observed in hydrophobic-water emulsions, [1][2][3][4] small water droplets (<100 mm), [5][6][7] and thin aqueous lms. 8,9 Reaction acceleration in these systems is oen accompanied by improved product selectivity, 6,[10][11][12][13][14] and some reactions which do not proceed in bulk water such as spontaneous hydrogen peroxide generation have been found to occur in these aqueous droplets. 7 These interface-rich systems have been proposed as the ideal environments for the origin of biogenic molecules [15][16][17] and reactions relevant to the origin of life have recently been reported in microdroplets.…”
