Mechanism‐Guided Engineering of Upconversion Nanoparticles for Antibacterial Phototherapy: From Photonic Principles to Translational Nanosystems

open access: yesSmall, EarlyView.
This review provides a systematic overview of the field of antibacterial PhotoDynamic Therapy (aPDT) triggered by upconversion nanoparticles (UCNPs), focusing on the mechanisms and the key factors that define their efficacy for generating bactericidal species upon NIR‐light activation.

Tailoring MXene Flake Morphology via Aerosol Jet Printing for Biological and Strain Sensor Applications

open access: yesSmall, EarlyView.
Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...

Nano‐Optical Biomolecular Interaction Sensing Within Complex Media via Peptide Hybrid Ligand Conjugation

open access: yesSmall, EarlyView.
We have designed a new type of nanoparticle‐based optical biosensor whose surface has been engineered with peptide‐polymer hybrids so that sensing of small protein‐protein interactions can be performed in simple buffers and complex biological liquids including animal and human serum. Measurements can be performed simply by mixing nanosensors with media

Induced Core‐Shell Transformation in Agarose‐Chitosan Nanoreactor Beads Enable Single Channel Coding for dPCR Multiplexing

open access: yesSmall, EarlyView.
Hybrid agarose–chitosan beads undergo a pH‐dependent reorganization into stable core–shell structures upon heating. The resulting tunable optical shell/core contrasts enable bead‐based coding for multiplex PCR. This approach allows sample multiplexing with simple detection systems and functionally exploits a previously unrecognized structure‐forming ...

Engineering an Enzymatically Active Granular Matrix for On‐Chip Modeling of Bone‐Like Mineralization

open access: yesSmall, EarlyView.
Alkaline phosphatase (ALP)‐functionalized poly(ethylene glycol) (PEG) microgels assemble into a perfusable granular matrix for cell‐free modeling of bone‐like mineralization. Microgel‐associated enzymatic activity promotes calcium phosphate deposition, producing a calcium‐deficient, poorly crystalline apatite‐like phase, while keeping interparticle ...

Designable Nanozymes for Site‐Selective Amide/Ester Hydrolysis

open access: yesSmall, EarlyView.
Enzymes involved in posttranslational modifications of proteins routinely perform site‐selective catalysis, regardless of the intrinsic reactivities of the myriad of functional groups present. Synthetic mimics of these enzymes are created through molecular imprinting, with catalytic groups positioned precisely near the targeted amide or ester bonds ...
