Rigid Hollow Microparticles for Enhanced Focused Ultrasound Treatment Under Optoacoustic Guidance

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
By combining focused ultrasound (FUS) and acoustically active hollow borosilicate microparticles (HBMPs), we demonstrate tunable control over interparticle dynamics and their localized thermal energy deposition. Modulation of acoustic frequency and particle concentration tailors the energy delivery, allowing adaptive, material‐based regulation of ...

Super-resolution photoacoustic imaging via flow induced absorption fluctuations

open access: yes, 2017
In deep tissue photoacoustic imaging the spatial resolution is inherently limited by the acoustic wavelength. We present an approach for surpassing the acoustic diffraction limit by exploiting temporal fluctuations in the sample absorption distribution ...

Precision medicine in cutaneous melanoma—A comprehensive review

open access: yesJournal of the European Academy of Dermatology and Venereology, Volume 40, Issue 3, Page 377-386, March 2026.
Precision medicine tailors treatment to each patient, beginning with detailed diagnostics. In melanoma, it has advanced considerably: Some methods are in practice and guidelines, while others are commercially available but not routine. This review highlights current and emerging approaches, including molecular profiling, imaging, biomarkers and AI ...

Photoacoustic generation by a gold nanosphere: From linear to nonlinear thermoelastics in the long-pulse illumination regime

open access: yes, 2015
We investigate theoretically the photoacoustic generation by a gold nanosphere in water in the thermoelastic regime. Specifically, we consider the long-pulse illumination regime, in which the time for electron-phonon thermalisation can be neglected and ...

Fluorescent proteins: A journey from the cell to extreme environments in material science

open access: yesPhotochemistry and Photobiology, Volume 102, Issue 2, Page 290-302, March/April 2026.
Applications of proteins and microorganisms as tools or effectors in material science. Abstract This review presents the progression from the use of fluorescent proteins (FPs) and chromoproteins as bioimaging labels and sensors to the strategic engineering of their properties for robust functionality in synthetic and non‐biological environments ...

Cold Quad‐Modal Nanocomplex for Precise and Quantitative In Vivo Stem Cell Tracking

open access: yesAdvanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
Multimodal albumin–bismuth sulfide–superparamagnetic iron oxide (ABS) nanocomplexes are developed for stem cell tracking across four different imaging modalities: MRI, MPI, MSOT, and CT. Combining its flexibility with high sensitivity, this quad‐modal imaging agent enables a robust quantification of ABS‐labeled stem cells in vivo.
