文摘
- •
This article shows preparation of highly charged NPs for the purpose of enhanced protein binding.
- •
The non-monotonic effect of ionic strength was observed and studied by qualitative and quantitative experiments.
- •
The protein charge anisotropy and electrostatic repulsion among NPs was concluded to control the non-monotonic ionic strength effects together.
