Swiss roll nanoarrays for chiral plasmonic photocatalysis.

Manipulating the chirality at nanoscale has drawn great attention among scientists, considering its pivotal role in various applications of current interest, including nano-optics, biomedicine, and photocatalysis. In this work, we delve into this arena by fabricating chiral Swiss roll nanoarray (SRNA) continuous films employing colloidal lithography. The technique permits the dimension of Swiss roll metamaterials to reduce to nanoscale, thus achieving chiroptical response (circular dichroism (CD)) in the visible region.

Association Between Metabolic Risk Factors and Cognitive Impairment in Schizophrenia Based on Sex.

Objective: Sex differences have been observed in many aspects of schizophrenia, including cognitive deficits. Despite extensive research into the relationship between metabolic factors and cognitive deficits in schizophrenia, few studies have explored the potential sex difference in their association.

Methods: We recruited 358 schizophrenia patients and 231 healthy controls.

Plasmonic Chiral Metamaterials with Sub-10 nm Nanogaps.

Sub-10 nm nanogaps are enantioselectively fabricated between two nanocrescents based on nanoskiving and show tailored circular dichroism (CD) activity. The mirror symmetry of the nanostructure is broken by subsequent deposition with different azimuthal angles. Strong plasmonic coupling is excited in the gaps and at the tips, leading to the CD activity.

[Determination of Six Ingredients in Gardenia jaminoides Fruits with Quantitative Analysis of Muti-components by Single Marker].

Objective: To establish a method of quantitative analysis of multi-components, by single marker(QAMS)for simultaneously determining six ingredients in Gardenia jasminoides fruits.

Methods: A multi-wavelength segmentation detection method was used. A methodological mode was found to analysis six ingredients in Gardenia jasminoides fruits by quantitative analysis of QAMS.
