Detection and Quantification of Spreading Depolarization in Drosophila melanogaster Using High‐Throughput, Wide‐Field Brain Imaging

Current Protocols, Volume 6, Issue 10, October 2026.
Abstract Spreading depolarization (SD) is a ubiquitous neural phenomenon implicated in mammalian neurological disorders including cerebral ischemia, brain death, stroke, brain injury, and migraine, as well as in insect chill coma. During SD, a breakdown of ion homeostasis and a slowly spreading wave of neural depolarization leads to processing deficits,

Study of a Frugal Design Picosecond Laser System for Laser‐Assisted Corneal Surgery

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Stromal surface after extraction of the lamella cut with the studied frugal picosecond laser source. ABSTRACT Femtosecond lasers have long been the gold standard for corneal laser‐assisted surgery, but their high cost limits widespread use. This study challenges their supremacy by investigating a cost‐effective alternative: a frugal all‐fiber ...

Two‐Photon Fluorescence and Second‐Harmonic Generation Microscopy: Principles and Biomedical Applications

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

Spiropyran‐Crosslinked PDMS Optical Waveguides for Pressure Sensing and Visual Cue of Localized Pressure Threshold

Polymers for Advanced Technologies, Volume 37, Issue 10, October 2026.
ABSTRACT Compliant optical waveguides are promising candidates for stress/strain sensing in soft robotics and personalized healthcare. While poly(dimethylsiloxane) (PDMS) offers a robust platform, enhancing sensitivity and integrating localized visual indicators for pressure threshold detection remains an active area of research.
