Ethenolysis as an on-purpose linker cleavage strategy for delamination of metal-organic frameworks

Rachel L. Mander, Nesha May Andoy, Ruby May A. Sullan, Maciej Damian Korzyński

Metal-organic frameworks (MOFs) are a unique class of hybrid organic-inorganic materials that distinguish themselves with their highly porous crystalline structures, making them desirable for a variety of applications. The successful implementation of MOFs in various industries relies on the ability to precisely …

Polymer Corona Architecture Modulates Nanoparticle–Bacteria Interactions and Photothermal Antibacterial Activity of Polydopamine Nanoparticles

Anna Galang, Nesha May O. Andoy, Ruby May A. Sullan

The global rise of antimicrobial resistance (AMR) threatens the efficacy of conventional antibiotics and demands new treatment strategies beyond molecular inhibition. Nanomaterials, particularly polydopamine nanoparticles (PDNPs), offer a promising non-antibiotic platform because of their biocompatibility, facile functionalization, and intrinsic photothermal activity, which …

Modeling cancer with bacteria-integrated tumor microenvironments using biomaterials: Emerging concepts and opportunities

Keuna Jeon, Uijin Kim, Chang-Hun Ji, Meenakshi Kamaraj et autres

The tumor microenvironment (TME) is a dynamic and heterogeneous ecosystem in which cancer, stromal, immune, and physicochemical components collectively regulate disease progression and therapeutic response. Recent evidence further indicates that intratumoral bacteria are active contributors to tumor metabolism, immune modulation, and treatment …

Reversible Fe 3+ Coordination Drives Polydopamine Nanoparticle Assembly for High Iron Loading and Ferroptosis Selectivity

Sadman Sakib, Renjie Cui, Nesha May Andoy, Wanyan Liu et autres

Polydopamine (PDA) nanomaterials are widely studied as biodegradable carriers for metal ions, particularly Fe³⁺, due to the strong affinity of catechol groups for iron. However, generating very small PDA nanoparticles with a high iron-loading capacity remains difficult. Here, we show that polymerizing …

Calpain small subunit homodimerization is robust and calcium‐independent

Nesha May O. Andoy, Trina Dykstra‐MacPherson, Mathias Bell, Peter L. Davies et autres

Calpains dimerize via penta‐EF‐hand (PEF) domains, but their mechanical stability and kinetics remain incompletely characterized. Here, we used single‐molecule force spectroscopy on an EGFP‐tagged calpain small subunit PEF (CAPNS1‐PEF) homodimer to quantify dissociation mechanics. Across retraction speeds of 0.2–10 μm/s, homodimer rupture …

Single‐Cell Force Spectroscopy Uncovers Root Zone‐ and Bacteria‐Specific Interactions

Yilei Xue, Mackenzie Eli William Loranger, Yifan Jia, Nesha May Andoy et autres

Understanding root-bacteria interactions with plant growth-promoting rhizobacteria (PGPR) is key to developing effective biofertilizers for sustainable agriculture. We performed single-cell force spectroscopy using the atomic force microscope (AFM) to study the primary attachment of two PGPR, Bacillus velezensis and Pseudomonas defensor, to …
