Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, Volume 36, Issue 58, 20 July 2026.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Diabetes screening by telecentric digital holographic microscopy [PDF]

Journal of Microscopy, 2015
SummaryDiabetes is currently the world's fastest growing chronic disease and it is caused by deficient production of insulin by the endocrine pancreas or by abnormal insulin action in peripheral tissues. This results in persistent hyperglycaemia that over time may produce chronic diabetic complications.

Red‐Sensitive Photopolymerizable Glass for Fabrication of Holographic Optical Elements

Advanced Optical Materials, Volume 14, Issue 28, 24 July 2026.
This study presents a novel photopolymerizable glass capable of optical patterning using red‐wavelength laser exposure. Red‐light sensitivity was achieved through the incorporation of a photoinitiating system composed of methylene blue (MB) and N‐phenylglycine (NPG).

Profiling Co‐Occurrent Morphological Phenotypes and Their Degree of Expression Severity in Vacuolated Cells by Holo‐Tomographic Flow Cytometry and Fractal Analysis

Advanced Intelligent Systems, Volume 8, Issue 7, July 2026.
HTFC gets 3D refractive index tomograms of flowing cells. Label‐free monocytes are engineered to express patterns of cytoplasmic vacuoles. From the tomogram, an efficient dimensionality reduction is operated. Interpretable features are extracted to classify the expression severity of phenotypes coexisting in each cell, visually represented by a seven ...

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

InfoMat, Volume 8, Issue 7, July 2026.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Noise Resilient Real‐Time Phase Imaging via Undetected Light

Advanced Quantum Technologies, Volume 9, Issue 7, July 2026.
Quantum imaging with undetected light enables decoupled illumination and detection, but real‐time operation under strong noise conditions remains challenging. By combining nonlinear interferometry with off‐axis holography, this work demonstrates real‐time amplitude and phase imaging at up to 4 Hz, even when noise exceeds the signal by an order of ...
