![]() ![]() Using a double-droplet microfluidics method, hexametaphosphate (HMP) chelating solution was encapsulated in an Fe3O4 nanoparticle (Fe3O4 NP)-loaded PLGA polymer shell with a thickness of 90%), and an effective removal efficacy (>95 %, 7 repeat cycles) of artificial calcium oxalate (5 mm in size) via a chelating effect. ![]() A novel urolithiasis treatment in which chelating solution encapsulated in poly(lactic-co-glycolic acid PLGA)-based microcapsules was delivered magnetically to specific urolithiasis sites and then subjected to ultrasound (US) to release the chelating solution and dissolve the stones.
