Cortisol is a steroid hormone that is released from the body in response to stress. Although a
moderate level of cortisol secretion can help the body maintain homeostasis, excessive …

During a stress condition, the human body synthesizes catecholamine neurotransmitters
and specific hormones (called “stress hormones”), the most important of which is cortisol …

Estrogenic compounds such as estrone (E1), 17β-estradiol (E2), and 17α-ethynylestradiol
(EE2) are serious environmental contaminants due to their potent biological activities. At …

With more and more new aptamers being reported, a general, cost-effective yet reliable
aptamer binding assay is still needed. Herein, we studied cationic conjugated polymer …

The utilization of structure-switching aptamers (SSAs) has enabled the development of novel
sensing platforms for the sensitive and continuous detection of molecules. De novo …

Using DNA staining dyes such as SYBR Green I (SGI) and thioflavin T (ThT) to perform label-
free detection of aptamer binding has been performed for a long time for both binding …

Abstract The WHO estimates that 8–10% of couples are facing fertility problems, often due to
inaccuracy in predicting the female's ovulation period controlled by four key hormones. The …

The reliable, readily accessible and label-free measurement of aptamer binding remains a
challenge in the field. Recent reports have shown large changes in the intrinsic fluorescence …

Estradiol (E2) and related estrogens are emerging environmental contaminants that may
adversely affect the health of humans, animals, and ecosystems. Many aptamers have been …

Cortisol is a key stress biomarker in humans and animals, including fishes. In aquafarming,
stress monitoring using cortisol quantification can help to optimize aquaculture practices for …
