Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, Volume 37, Issue 48, December 3, 2025.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

Advanced Science, Volume 12, Issue 47, December 18, 2025.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Noninvasive Detection and Thermal Ablation Therapy of Endometriosis Using Silica‐Coated Gold Nanorods

Advanced NanoBiomed Research, Volume 5, Issue 12, December 2025.
AuNR@Si(F)‐PEG nanoparticles are developed as theranostic agents for the noninvasive detection and photothermal therapy of endometriosis. The particles are preferentially taken up by the endometriosis lesions under photoacoustic image‐guidance, and used as thermal ablation therapeutics to shrink the lesions.

Current and Emerging Clinical Applications of Multispectral Optoacoustic Tomography (MSOT) in Oncology [PDF]

Clinical Cancer Research, 2016
Abstract Accurate detection and characterization of cancers are key for providing timely intervention and effective treatments. Current imaging technologies are particularly limited when it comes to detecting very small tumors in vivo, i.e., very early cancers or metastases, differentiating viable tumor from surrounding dead tumor tissue,

S1 guideline for imaging diagnostics for skin diseases

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 23, Issue 12, Page 1616-1630, December 2025.
Summary Non‐invasive imaging techniques allow a quick and easy in vivo examination of the skin with different penetration depths and resolution depending on the applied technology. Established methods such as dermoscopy and high‐resolution sonography of the skin have been an integral part of everyday life for decades.
