Research on the construction of portable electrochemical sensors for environmental

Quanguo He et al.

Summary: The environment is crucial for human survival, but human activities have led to increasing pollutants in drinking water, food, and the environment, posing a significant threat to human health. Therefore, there is a need for fast and effective monitoring of environmental compound concentrations in samples. Electrochemical sensors have great potential for online monitoring of specific pollutants in complex environments due to their high sensitivity, selectivity, low cost, simplicity, and accuracy, making them a hot research topic. With the development of portable electronic technology, portable electrochemical sensing systems have seen significant growth in various fields. This paper provides a systematic review of portable electrochemical sensors used for environmental pollutant analysis and summarizes the current research direction, aiming to inspire researchers with new ideas and perspectives.

Latest research progress on anticancer effect of baicalin and its aglycone baicalein

Lin Wang et al.

Summary: Baicalin and baicalein, derived from Scutellaria baicalensis Georigi, have remarkable anticancer activities by inducing apoptosis, cell cycle arrest, suppressing metastasis, inducing autophagy, and regulating immunity. Baicalein shows quicker and stronger inhibitory effects on multiple cancers compared to baicalin, possibly due to its smaller size and high lipophilicity.
