Photoacoustic/Ultrasound Dual‐Modality Imaging Nomogram for Diagnosing Nonmelanoma Skin Cancer: A Preliminary Diagnostic Accuracy Study

Dermatologic Therapy, Volume 2026, Issue 1, 2026.
Objective Nonmelanoma skin cancer is among the most common malignancies worldwide, with rising incidence. Early and accurate diagnosis is critical for improving prognosis. This study aims to develop, with internal validation, a multiparametric nomogram based on photoacoustic and ultrasound dual‐modality imaging for the differential diagnosis of NMSC ...

Frontiers in Neurotransmitter Probes: Innovations and Perspectives in Norepinephrine Detection Technology

Journal of Analytical Methods in Chemistry, Volume 2026, Issue 1, 2026.
Norepinephrine (NE), the primary neurotransmitter of locus coeruleus projections, plays a crucial role in regulating arousal, emotion, memory, and stress responses. Its dysregulation is closely associated with various neurological disorders such as depression, Parkinson’s disease, and epilepsy.

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

Advanced Materials, Volume 37, Issue 49, December 10, 2025.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

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.
