Biosurfaces Fabricated by Polymerization-Induced Surface Self-Assembly
Langmuir, 2020Surface biofunctionalization provides an approach to the fabrication of surfaces with improved biological and clinical performances. Biosurfaces have found increasing applications in many areas such as sensing, cell growth, and disease detection. Efficient synthesis of biosurfaces without damages to the structures and functionalities of biomolecules is

ROMPISA: Ring-Opening Metathesis Polymerization-Induced Self-Assembly
ACS Macro Letters, 2017Herein we report a polymerization-induced self-assembly (PISA) process with ring-opening metathesis polymerization (ROMP). We utilize a peptide-based norbornenyl monomer as a hydrophobic unit to provide a range of nanostructures at room temperature yet at high solids concentrations of 20 wt % in combination with an oligoethylene glycol based ...

Ultrafast Xanthate‐Mediated Photoiniferter Polymerization‐Induced Self‐Assembly (PISA)
Angewandte Chemie International Edition, 2023AbstractPolymerization‐induced self‐assembly (PISA) is a powerful technique for preparing block copolymer nanostructures. Recently, efforts have been focused on applying photochemistry to promote PISA due to the mild reaction conditions, low cost, and spatiotemporal control that light confers.

Photo-PISA: Shedding Light on Polymerization-Induced Self-Assembly
ACS Macro Letters, 2015Herein we report an aqueous photoinitiated polymerization-induced self-assembly (photo-PISA) for the preparation of a remarkably diverse set of complex polymer nanoparticle morphologies (e.g., spheres, worms, and vesicles) at room temperature. Ultrafast polymerization rates were achieved, with near quantitative monomer conversion within 15 min of ...

Reactive and Functional Nanoobjects by Polymerization‐Induced Self‐Assembly
Macromolecular Rapid Communications, 2018AbstractPolymerization‐induced self‐assembly (PISA) is becoming a standard technique for generating core–shell polymeric nanoparticles of various morphologies ranging from classic spheres to rods/fibers (“worm‐like”) and vesicles. After the initial quest for polymerization control in dispersed media, the focus of PISA research has drastically shifted ...

Self-assembly of nanoparticles employing polymerization-induced phase separation
Journal of Colloid and Interface Science, 2014Nanoparticles (NPs) may be homogeneously dispersed in the precursors of a polymer (reactive solvent) by an adequate selection of their stabilizing ligands. However, the dispersion can become metastable or unstable in the course of polymerization.

Gradient Polymerization–Induced Self‐Assembly: A One‐Step Approach
Macromolecular Rapid Communications, 2019AbstractIn this work, the authors report a novel single‐step, one‐pot process for the synthesis of self‐assembled nanoparticles using a polymerization‐induced self‐assembly (PISA) mechanism. In contrast to conventional approaches employing a pre‐formed macromolecular stabilizer, the disparate reactivities between two monomers, oligo(ethylene glycol ...
