a Selected SEM and e TEM image for CHX-loaded/MSN. Associated TEM-EDS elemental analysis confirming the presence of b oxygen, c silica, and d carbon for CHX-loaded/MSN. fi Associated EDS elemental analysis and j TEM image of the CHX-loaded/MSN-PLGA nanoparticles. The Carbon (h) is associated with PLGA modification and chlorine (f) and nitrogen (g) from chlorhexidine. CHX-loaded/MSN nanoparticles exhibited a more uniform morphology with relatively larger particle size compared to CHX-loaded/MSN-PLGA which showed more irregular particle morphology
