A simple far-red fluorescent probe was developed to monitor mercury ions in environmental water samples and in living systems.

A simple colorimetric and far-red fluorescent probe was developed for the first time to visualize the gasotransmitter carbon monoxide in subcellular mitochondria.

A simple highly specific fluorescent probe was reasonably constructed to simultaneously detect Cys/Hcy and GSH/H2S in living cells and zebrafish using two separated fluorescence channels under single wavelength excitation.

A dual-mode self-powered aptasensing platform of photoelectrochemical (PEC) and photofuel cell (PFC) was constructed for Microcystin-LR (MC-LR) detection. Specifically, the In2O3–In2S3–Ti3C2 (IO–IS–TC) composite was facilely assembled on the base of MOF-derived In2O3 hollow tubulars, and the integrated mechanism and photoconversion efficiency are proposed and discussed in detail. Herein, a promising dual-mode sensing platform was constructed using the IO–IS–TC composite as a photoanode matrix with higher output power and obvious photocurrent response. Moreover, the dual-mode sensing platform did not require external bias and the addition of sacrificial agents under visible light irradiation. The enhanced PEC properties can be attributed to the matched energy level of ternary components and the improved separation of photogenerated carriers. Moreover, aptamer-based recognition was adopted to catch MC-LR molecules, which realized the highly sensitive and selective detection. The PFC aptasensor was exhibited at 50–5 × 105 pmol/L with a detection limit of 17.4 pmol/L, and the PEC aptasensor was realized from 0.5 to 4 × 105 pmol/L with a detection limit of 0.169 pmol/L. The proposed aptasensing platform showed good specificity, reproducibility, and stability, which paved the way for the construction of a fast and ultrasensitive PEC sensing methodology for environmental analysis.

Background: Breastfeeding is the most effective way to provide food for the healthy growth and development of babies. It has been reported in the literature that interventions on parturients, with the theory of planned behavior (TPB) as the guiding framework, can achieve good results. The purpose of the present study was to explore the effect of the TPB on primipara breastfeeding.Methods: A total of 70 primiparas, who were given regular intervention mode at Haian People's Hospital from May 2017 to May 2018, were selected as the control group, and a total of 70 primiparas, who were given the TPB model from June 2018 to June 2019, were selected as the observation group. Exclusive breastfeeding rates, continuous breastfeeding rates, and breastfeeding confidence and breastfeeding impact factors were compared between the two groups.Results: After the intervention, the pure breastfeeding rates of the observation group at discharge, 1 month after delivery, and 4 months after delivery were higher than those of the control group (P<0.05).After intervention, the continuous breastfeeding rates of the observation group was higher than that of the control group at 4 months after delivery (P<0.05). After intervention, the skill dimension, inner activity dimension, and total score of the observation group were higher than those of the control group (P<0.05).After intervention, scores of attitude, perceptual behavior control, and knowledge in the observation group were higher than those of the control group (P<0.05). Conclusions:The application of the TPB to primipara breastfeeding can significantly increase the rate of exclusive breastfeeding and continuous breastfeeding, and effectively improve the impact factors of breastfeeding.
