Time kill assay of imipenem/cilastatin loaded polycaprolactone nanoparticles (IMP/PCL), and imipenem/cilastatin loaded polylactide-co-glycolide nanoparticles (IMP/PLGA) against a Klebsiella pneumoniae KMU5.5 and b Pseudomonas aeruginosa PUMU2.3. Low concentration of IMP/PCL (5-10 µg/ml) caused rapid and significant decrease in bacterial count within 2–3 h of interaction (*significant difference P < 0.05)
