In Vitro Evaluation of Curcumin-Encapsulated Chitosan Nanoparticles against Feline Infectious Peritonitis Virus and Pharmacokinetics Study in Cats

Table 2

Characterisation parameters of chitosan nanoparticles and Cur-CS nanoparticles.

	Chitosan/curcumin ratio	Mean particle size (nm)	Zeta potential (mV)	Encapsulation efficacy (%)	Drug loading (%)
Cur-CS nanoparticles	1 : 1	^a	ND	^a	^a
	1 : 0.75	^b		^b	^b
	1 : 0.5	^b	ND	^b	^b
Chitosan nanoparticles		^c		—	—

Data are presented as () and analysed using one-way ANOVA and post hoc Duncan multiple test. For each parameter, means within a column with different roman letters were significantly different () from each other. Cur-CS: curcumin-encapsulated chitosan; ND: not determined.
