Targeted nanotherapeutics for the treatment of Helicobacter pylori infection

Journal of Biomedical Science
Helicobacter pylori infection is involved in gastric diseases such as peptic ulcer and adenocarcinoma. Approved antibiotherapies still fail in 10 to 40% of the infected patients and, in this scenario, targeted nanotherapeutics emerged as powerful allies ...

Size-dependent bioactivity of electrosprayed core–shell chitosan-alginate particles for protein delivery

Scientific Reports, 2022
Nano-bio interactions are size-dependent. The present study investigates whether core–shell chitosan-alginate particle size governs biological activities as well as protein release profile.

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Release retardation of model protein on polyelectrolyte-coated PLGA nano- and microparticles. [PDF]

PLoS ONE, 2014
PEM capsules have been proposed for vehicles of drug microencapsulation, with the release triggered by pH, salt, magnetic field, or light. When built on another carrier encapsulating drugs, such as nanoparticles, it could provide additional release ...

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Metal–Phenolic Coatings Enable Universal Design of Spherical Nucleic Acids

Angewandte Chemie, EarlyView.
A general and straightforward strategy for constructing spherical nucleic acids (SNAs) using metal–phenolic (MP) coatings has been developed. The resulting MP‐SNAs exhibit many of the hallmark SNA properties, including enhanced cellular uptake, and serve as versatile building blocks for the programmable assembly of a diverse library of nanoparticles ...
