Research on cognitive neural mechanism of consumers convinced by intelligent recommendation platform eavesdropping.

The negative inference that consumers hold 'eavesdropping' views concerning the intelligent recommendation services of digital platforms is fostering their selective exposure to information that aligns with their preferred viewpoints. This, in turn, exacerbates their psychological defense against digital platforms, causing consumers to become more prone to verifying existing beliefs and fostering the polarization of information choices. This phenomenon directly impacts the effectiveness of smart recommendations and the accuracy of digital platforms' predictions of consumer behavior, potentially even adversely affecting brand trust and the long-term stability of platform usage.

Leveraging the dynamic boronic ester bonds, BN coordination, and π-π stacking, the nanovehicles reveal remarkably efficient and robust drug coencapsulation.

The Accurate Imaging of Collective Gold Nanorods with a Polarization-Dependent Dark-Field Light Scattering Microscope.

Anisotropic nanomaterials, such as gold nanorods (AuNRs), could be employed as an orientation platform due to their polarization-dependent surface plasmon resonance. However, a variety of factors would affect the dark-field light scattering imaging of anisotropic nanomaterials, resulting in an unstable signal, which is not advantageous to its further application. In this work, the localized surface plasmon resonance properties of a few AuNRs at different angles were excited by polarization with a conventional dark-field microscope, in which it was found that the ratio of AuNRs' light scattering intensity at different polarization angles () to that without a polarizer () reflected the orientation information of AuNRs.

The restructure of Au@Ag nanorods for cell imaging with dark-field microscope.

The facile and noninjurious image of cells with high resolution and low toxicity is essential since imaging can offer rich and direct information and insights into metabolic activities, clinical diagnosis, drug delivery and cancer therapy. In this contribution, a smart imaging probe was employed as a contrast agent for dark-field cell imaging. Au core/Ag shell nanorods (Au@Ag NRs) that characterized by X-ray diffraction and X-ray photoelectron spectroscopy, formed Au@Ag@AgI NRs when exposed to iodine, which greatly enhanced the light scattering of nanorods.

"Hepatitis virus indicator"----the simultaneous detection of hepatitis B and hepatitis C viruses based on the automatic particle enumeration.

As the common hepatitis viruses, hepatitis B virus (HBV) and hepatitis C virus (HCV) are important causes of liver diseases, which greatly threaten human health and public hygiene. Furthermore, due to the similar transmission routes of HBV and HCV, it is highly susceptible to suffer from the cross-infection of HBV and HCV when humans are infected by hepatitis viruses. So it is urgent to develop strategies with high sensitivity to distinguish HBV/HCV and detect their overlapping infection.

MicroRNAs, as one kind of significant biomarkers, play indispensable roles in the diagnosis and treatment of cancers. Yet, owing to low expression and high sequence homology, high sensitivity and specificity for microRNA detection are greatly challenging. Herein, a sensitive sensing platform with high specificity was developed for microRNA-27a (miRNA-27a) based on the miRNA-27a-triggered chemical etching of gold nanorods to a smaller size, which was accompanied by a significant blue shift and a large decrease of intensity in the localized surface plasmon resonance (LSPR) scattering and remarkable color variability from red to green.

MicroRNAs involved in tumor-related tissues at abnormal expression level present tremendous potential in the early diagnosis of cancers. However, their intrinsic shortcomings, for instance, low abundance and high sequence homology, make it challengeable to quantify them with high sensitivity and selectivity. Herein, a highly sensitive platform with great specificity was developed for microRNA-21 based on the produced-I triggered chemical etching of gold nanorods to a smaller size, resulting in a significant blue shift and a great intensity decrease in the localized surface plasmon resonance (LSPR) scattering.

Size-dependent light scattering of CoOOH nanoflakes for convenient and sensitive detection of alkaline phosphatase in human serum.

As a natural enzyme, alkaline phosphatase (ALP) plays an essential role in clinicopathological examinations and biomedical research, and is capable of hydrolyzing the phosphate group of l-ascorbic acid-2-phosphate (AAP) to yield l-ascorbic acid (L-AA). L-AA reduced cobalt oxyhydroxide (CoOOH) nanoflakes to Co , leading to a smaller size and weaker light scattering, which could be monitored by electron microscopic images and optical spectra. The indirect detection of ALP was achieved by the reduced light scattering signal of CoOOH nanoflakes.
