“…[ 19,39,42–44 ] Also, they can be applied onto both curved and planar macroscale substrates. [ 18,44–47 ] For example, CSNP‐PDMS composites were applied onto concave substrates such as lenses, for use in high intensity focused ultrasound, [ 18,19,45,48 ] a therapeutic modality with wide‐ranging medical applications including tumor therapy, [ 49 ] drug delivery, [ 50,51 ] and tissue ablation. [ 52,53 ] Many studies that have focused on developing CSNP composites for OpUS generation have demonstrated promising results when these composites have been produced as free‐standing membranes.…”
