Designing Self-floating Anisotropic Macroporous Hydrogel by Step Emulsification and Buoyancy-assisted Microfluidics

Hydrogel: a new material for intravesical drug delivery after bladder cancer surgery

“…Floating platform hydrogels increase buoyancy by generating microbubbles within the hydrogel, allowing them to float in the urine inside the bladder. 91 This addresses the issue of potential irritation caused by the hydrogel sticking to the bladder wall. Even after urination, a small amount of urine remains in the bladder under normal conditions, ensuring that the floating platform hydrogel can constantly float without obstructing the urethra.…”

Hydrogels for Mucosal Drug Delivery

“…Emulsion gelation is another technique used to make floating hydrogels. Here, oil droplets are encapsulated within hydrogels during cross-linking to decrease the hydrogel density in aqueous solution to form floating hydrogels. , Other reported floating hydrogel designs include hydrophobic hydrogels, superporous hydrogels, and hydrogel rafts. ,,− …”
