AI Article Synopsis
- Six-particle and eight-particle plasmonic nanoantennas are designed to achieve a wide spectral response under circular and elliptical polarization.
- The common-gap configuration enhances the system's sensitivity to various light polarizations, overcoming the limitations of typical dipole antennas.
- The system's spectral characteristics can be adjusted by altering geometric parameters and varying the ellipticity of the incoming light.
Article Abstract
Six-particle and eight-particle common-gap plasmonic nanoantennas are utilized to obtain a broadband spectral response when illuminated with circular and elliptical polarization. Due to the insensitivity of dipole antennas to circular polarization, the resonant structures are brought together around the common-gap to expand the spectrum of the whole system. Their ability to focus light at different frequencies is demonstrated. The spectral response is manipulated by geometrical parameters and the strength of the spectral peaks is tailored through the ellipticity of the elliptically polarized light.

Superior to traditional multiplex photoelectrochemical (PEC) sensors, integrated multitarget assay on a single reconstructive electrode interface is promising in real-time detection through eliminating the need of specialized instrumentation and cumbersome interfacial modifications. Current interface reconstruction approaches including pH modulation and bioenzyme cleavage involve biohazardous and time-consuming operations, which cannot meet the demand for rapid, eco-friendly, and portable detection, which are detrimental to the development of multiplex PEC sensors toward portability. Herein, we report a pioneer work on IR-driven "four-to-one" multisignal conditioning to facile reconfigure electrode interface for multitarget detection via photoelectrochemical/photothermal dual mode.

Background: Dementia exhibits abnormal network activity, including altered gamma frequency (30-100 Hz) in Alzheimer's disease (AD). A non-pharmacological, non-invasive approach to AD treatment involves stimulating sensory inputs using gamma band, with 40 Hz as the most effective in eliciting a robust EEG response. Light and sound stimulation at 40 Hz reduces AD pathology in mouse models and improves cognition in humans with AD.

Background: Alzheimer's disease is defined by the pathological aggregation of amyloid-beta and hyperphosphorylated tau. AD patients often exhibit other symptoms like metabolic and sleep dysfunction. Currently, it is unclear if impairments are a cause or consequence of Aβ or tau aggregation.

Background: Microglial reactivity and neuroinflammation are crucial pathological processes in Alzheimer's Disease (AD). Several attempts to develop a treatment by supressing the immune response in AD have been made, yet these yielded very limited results. Recent studies suggest contrasting effects of microglial reactivity, indicating a biphasic response with both beneficial and deleterious effects at distinct stages of AD.
