The Rachel O'Reilly group is based in the School of Chemistry at the University of Birmingham: https://oreillygrouplab.com/ We create self-assembling ‘living machines’, fluorescent probes, and molecules capable of precisely controlled release.

My colleague Helen Fielding is organising the 2026 Women in Photochemistry Symposium at @uclchemistry.bsky.social on Wednesday the 4th of March with talks by Susannah-Bourne-Worster (Durham), Maria Sanz (King's College) and Marsha Lester (UPenn). www.eventbrite.co.uk/e/women-in-p... #chemsky

ROR group @uobchemistry.bsky.social and researchers at Shanghai and Zhejiang Sci-Tech universities develop a light-activated “nanopatch” that sticks to tumour cells and stresses their membranes, also promoting the release of antigens: pubs.acs.org/doi/full/10.... @tianlaixia.bsky.social #Chemsky

NIR-Actuated Morphodynamic 2D Nanopatches for Interface-Programmed Immunoactivation and Tumor Regression

Achieving precise spatiotemporal modulation of immunostimulatory effects remains a fundamental barrier in tumor immunotherapy, particularly in the context of limited tumor antigen exposure and an immunosuppressive microenvironment. Herein, we present a light-responsive “dynamic nanopatch” platform that addresses these challenges through morphology-directed and interface-programmed immunoactivation. Constructed from crystalline poly(ε-caprolactone) and integrated with photothermal conversion elements, the nanopatch undergoes a near-infrared (NIR)-triggered morphology-dynamic transition from a two-dimensional planar structure to a zero-dimensional spherical counterpart. This dynamic structural transformation enables programmable interactions with the cellular membrane, establishing a versatile nanointerface capable of the in situ regulation of cancer cell membrane integrity. Upon NIR irradiation, the nanopatch stably adheres to the tumor cell surface and initiates a cascade of adhesion, deformation, and internalization events. This process promotes localized mechanical stress and membrane perturbation, enhancing the release of tumor-associated antigens and damage-associated molecular patterns, which collectively initiate potent immunogenic cell death. Subsequent activation of antigen-presenting cells leads to robust adaptive immune engagement and amplified immune cell infiltration within the tumor microenvironment. This morphodynamic nanopatch offers a highly controllable strategy for cancer immunotherapy and a new paradigm for interface-programmed functionalities with broad implications for precision medicine, immunotherapy, and biomaterial engineering.
