Multifunctional H2S‐activated metal‐organic framework systems for targeted colorectal cancer imaging and synergistic copper‐induced tumor regression

open access: yesBMEMat, EarlyView.
The in situ reaction of Cu‐MOFs with endogenous H2S enabled PA imaging and facilitated combined PTT/chemotherapy for colorectal cancer therapy. Abstract Stimuli‐responsive nanomaterials offer significant potential for enhancing diagnostic accuracy, optimizing therapeutic efficacy, and advancing precision theranostics.

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks

open access: yesChemistry – A European Journal, EarlyView.
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...
