Dual‐Target Nectin‐4/FAP Heterobivalent Probe 68Ga/177Lu‐FZ‐NF‐1 for Triple‐Negative Breast Cancer: Preclinical Theranostic Evaluation and First‐in‐Human Translation

Advanced Science, EarlyView.
A novel hetero‐bivalent agent, 68Ga/177Lu‐FZ‐NF‐1, concurrently targets Nectin‐4 and FAP in triple‐negative breast cancer. It yields significant preclinical tumor regression and clinically identifies additional metastatic lesions missed by 18F‐FDG PET, demonstrating promising theranostic potential for personalized management.

Retrospective dosimetry using salted snacks and nuts : A feasibility study

, 2017
The possibility of using ordinary household table salt for dosimetry is suggested by its high sensitivity to ionising radiation, which generates a readout of optically stimulated luminescence (OSL).

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides

Advanced Science, EarlyView.
Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...

Comparative Evaluation of Chelator‐Conjugated Peptides for Lead‐Labeled SSTR2‐Targeted Theranostics: Integrated Computational Modeling and Preclinical Validation

Advanced Science, EarlyView.
The study integrates density functional theory with radiochemical and biological validation to compare DOTA‐, PSC‐, and DOTAM‐based chelator‐conjugates for 203Pb/212Pb theranostic applications. Distinct differences in metal coordination, electrostatic properties, conformational flexibility, cellular uptake, biodistribution, and dosimetry are identified
