Improving ARTs: Microfluidics as a Tool for Sperm Selection

open access: yesAndrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Dynamic Generation of Spatially Variable Vector Beams Using Cascaded Moiré Metasurfaces

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
A three‐layer cascaded moiré metasurface dynamically generates vector beams with tunable polarization order and controllable lateral focal positions. Relative rotation of the first two layers adjusts the conjugate OAM components that form the vector beam, whereas the third layer steers its focus across the transverse plane, preserving the dominant OAM ...

High‐Power Continuous‐Wave Optical Waveguiding in a Semiconductor Nanowire

open access: yesAdvanced Photonics Research, Volume 7, Issue 9, September 2026.
An in‐line fiber–nanowire–fiber configuration provides efficient coupling of 1550 nm continuous‐wave light into and out of a single CdS nanowire. The output power increases linearly with input power, reaching 1.8 W and corresponding to a guided power of 2.5 W, demonstrating watt‐level continuous‐wave optical waveguiding in a subwavelength semiconductor

Modeling and Evaluation of Penetration Process Based on 3D Mechanical Simulation

open access: yesSensors
In biological micromanipulation, cell penetration is a typical procedure that precedes cell injection or oocyte enucleation. During this procedure, cells usually undergo significant deformation, which leads to cell damage.
