Dendrimer crosslinked γ-polyglutamic acid/sodium alginate sponges: enhanced hemostasis and sustained anti-inflammatory activity for post-sinusitis surgery treatment.
Sinusitis often requires functional endoscopic sinus surgery (FESS), but postoperative bleeding and persistent inflammation remain critical challenges. This study developed a multifunctional composite sponge (GSPB) using γ-polyglutamic acid (γ-PGA) and sodium alginate (SA) as the matrix, with Generation 3 polyamidoamin...
