(a) Correlation of the lateral size L0 of the initially shrunk microbubbles and the width Lw of the microwells. The value L0 approximately linearly increases with Lw. This implies that the larger well contains more entrapped gas. (b) Contact angle θ of the entrapped microbubbles as a function of L0. The contact angle decreases with increasing L0.
