Isolation Techniques of Micro/Nano‐Scaled Species for Biomedical Applications

Advanced Science, EarlyView.
Separating micro/nano‐scale bioparticles from samples is essential for disease diagnosis, prevention, and monitoring. Therefore, a comprehensive overview of the latest advanced separation technologies is provided, and characteristics and limitations based on six key performance parameters, including purity, recovery rate, throughput, resolution, size ...

Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet

Advanced Science, EarlyView.
The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.

Machine learning-enhanced optical tweezers for defect-free rearrangement [PDF]

arXiv
Optical tweezers constitute pivotal tools in Atomic, Molecular, and Optical(AMO) physics, facilitating precise trapping and manipulation of individual atoms and molecules. This process affords the capability to generate desired geometries in both one-dimensional and two-dimensional spaces, while also enabling real-time reconfiguration of atoms.

Magnetic‐Guided Delivery of Antisense Oligonucleotides for Targeted Transduction in Multiple Retinal Explant and Organoid Models

Advanced Science, EarlyView.
Magnetic field‐guided MNP@ATR‐ASO nanocomplexes facilitate the targeted delivery of ASOs to ganglion cells or photoreceptors within retinal explants, thereby enhancing the efficacy of ASOs in correcting pre‐mRNA splicing abnormalities. Furthermore, the nanocomplexes improve ASO penetration and delivery in human retinal and inner ear organoid models ...

Alignment and Optimisation of Optical Tweezers on Trapped Ions [PDF]

arXiv
This paper presents a routine to align an optical tweezer on a single trapped ion and use the ion as a probe to characterize the tweezer. We find a smallest tweezer waist of $2.3(2)\,\mu$m, which is in agreement with the theoretical minimal attainable waist of $2.5(2)\,\mu$m in our setup.

Instant Writing of Conductive Interface on MOF Single Crystal by Ultrafast Laser

Advanced Science, EarlyView.
Current device fabrication strategies lack capacity for tailoring ideal electrical interface in individual MOF single crystals. An ultrafast laser approach is developed that in situ constructs stable conductive interface on MOF single crystal scale while maintaining its crystalline integrity.
