Eigenspectra optoacoustic tomography achieves quantitative blood oxygenation imaging deep in tissues

, 2015
Light propagating in tissue attains a spectrum that varies with location due to wavelength-dependent fluence attenuation by tissue optical properties, an effect that causes spectral corruption.

Gamma probe and ultrasound guided fine needle aspiration cytology of the sentinel node (GULF) trial [PDF]

, 2017
Background: Sentinel node (SN) biopsy (SNB) detects clinically occult metastases of breast cancer and melanoma in 20-30%. Wound infections, seroma and lymph edema occur in up to 10%.

Multi-Aspect Optoacoustic Imaging of Breast Tumors under Chemotherapy with Exogenous and Endogenous Contrasts: Focus on Apoptosis and Hypoxia

Biomedicines, 2021
Breast cancer is a complex tumor type involving many biological processes. Most chemotherapeutic agents exert their antitumoral effects by rapid induction of apoptosis.

Aperiodic String Transducers

, 2016
Regular string-to-string functions enjoy a nice triple characterization through deterministic two-way transducers (2DFT), streaming string transducers (SST) and MSO definable functions. This result has recently been lifted to FO definable functions, with

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

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.

Multispectral optoacoustic tomography (MSOT): Monitoring neurovascular changes in a mouse repetitive traumatic brain injury model

Journal of Neuroscience Methods, 2023
Evidence suggests that mild TBI injuries, which comprise > 75% of all TBIs, can cause chronic post-concussive symptoms, especially when experienced repetitively (rTBI). rTBI is a major cause of cognitive deficit in athletes and military personnel and is associated with neurovascular changes.

Engineering gold nanotubes with controlled length and near-infrared absorption for theranostic applications [PDF]

, 2015
Important aspects in engineering gold nanoparticles for theranostic applications include the control of size, optical properties, cytotoxicity, biodistribution, and clearance. In this study, gold nanotubes with controlled length and tunable absorption in
