Plant‐Produced Viral Nanoparticles Decorated with Nanobodies Against HER2 Improve Retention and Recruitment of Immune Cells in Solid Tumors

Advanced Healthcare Materials, EarlyView.
Potato virus X is a filamentous RNA plant virus that can be engineered into a molecular tool for cancer therapy. We produced genetically‐encoded virus‐derived nanoparticles decorated with nanobodies targeting cancer cell receptors, epidermal growth factor receptor (EGFR) and human epidermal growth factor 2 (HER2).

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Ultrafast Xanthate‐Mediated Photoiniferter Polymerization‐Induced Self‐Assembly (PISA)

Angewandte Chemie International Edition, 2023
AbstractPolymerization‐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.

Ethylene‐Coordinative Chain‐Transfer Polymerization‐Induced Self‐Assembly (CCTPISA)

Chemistry – A European Journal, 2022
AbstractBlock copolymers based on ethylene (E) and butadiene (B) were prepared using the ansa‐bis(fluorenyl) complex {Me2Si(C13H8)2Nd(BH4)2Li(THF)}2 in combination with (n‐Bu)(n‐Oct)Mg (BOMAG) as a chain‐transfer agent. The diblock copolymers incorporating a soft poly(ethylene‐co‐butadiene) segment, called ethylene butadiene rubber (EBR), and a hard ...
