Nano-drug delivery system for pancreatic cancer: A visualization and bibliometric analysis.

Nano drug delivery system (NDDS) can significantly improve the delivery and efficacy of drugs against pancreatic cancer (PC) in many ways. The purpose of this study is to explore the related research fields of NDDS for PC from the perspective of bibliometrics. Articles and reviews on NDDS for PC published between 2003 and 2022 were obtained from the Web of Science Core Collection.

Self-assembly of polyelectrolyte diblock copolymers at monovalent and multivalent counterions.

In this work, the self-assembly behaviors of diblock copolymers consisting of one hydrophobic block and one ionizable polyelectrolyte (PE) block in the presence of monovalent and multivalent counterions are systematically discussed through molecular dynamics simulation. Copolymers are molded as bead-spring chains and the ions are explicitly considered. First, the self-assembled structures of symmetrical block copolymers at different charge fractions are analyzed in detail.
