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.

Microporous Polymer Membranes: Molecular Stents Enhanced Solvent‐Accessibility for Organic Solvent Transport

Advanced Science, EarlyView.
A novel microporous polyimide (PI‐TB‐NDI) is designed for enhanced organic solvent nanofiltration. By incorporating o‐methyl groups into the Tröger's base (TB) unit to create molecular stents, the polymer's intrinsic free volume is effectively increased without the need for post‐treatment.

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 ...

Feedback Intensity Equalization Algorithm for Multi-Spots Holographic Tweezer [PDF]

arXiv
High degree of adjustability enables the holographic tweezer array a versatile platform for creating an arbitrary geometrical atomic array. In holographic tweezer array experiments, an optical tweezer generated by a spatial light modulator (SLM) usually is used as a static tweezer array.

LRRC4 Deficiency Drives Premature Ovarian Insufficiency by Disrupting Metabolic Homeostasis in Granulosa Cells

Advanced Science, EarlyView.
LRRC4 deficiency disrupts the metabolic homeostasis of mitochondrial aerobic respiration and glycolysis during GC differentiation by inhibiting the ubiquitination‐mediated degradation of YAP, which ultimately leads to POI. These findings reveal the novel molecular etiology of POI and provide a promising target for prevention and treatment.

High spatiotemporal resolution data from a custom magnetic tweezers instrument

Data in Brief, 2020
Gene expression is achieved by enzymes as RNA polymerases that translocate along nucleic acids with steps as small as a single base pair, i.e., 0.34 nm for DNA.
