Summary: The real-time detection of formaldehyde is crucial for environmental pollution monitoring and healthcare. In this study, indium-doped LaFeO3 porous structure was synthesized to enhance the sensing capability. The results showed that the response value of the material towards 100 ppm formaldehyde at the optimal temperature of 125 degrees C was 122, which was twice the value of the pristine material. Importantly, the sensor demonstrated a distinct response even at a concentration as low as 1 ppb, which is the lowest detection limit reported so far. The improved sensing performance was attributed to the increased surface area, abundant oxygen vacancies, and reduced surface adsorption energy. These findings suggest that indium-doped LaFeO3 is a promising material for practical formaldehyde sensing applications.

Summary: A novel formaldehyde sensor was developed by combining 2D graphitic carbon nitride (g-C3N4) nanosheets and In2O3 nanospheres. SEM, TEM, XRD and XPS were used to analyze the samples. Compared to pure In2O3 nanospheres, the 20% g-C3N4/In2O3 sensor exhibited optimal response (59.94) and faster response time (8 s) at a lower operating temperature of 120 degrees C. It also showed excellent selectivity and long-term stability. The improved sensing properties can be attributed to the defects and charge transfer in the g-C3N4/In2O3 n-n heterojunction and large surface areas. This work provides a method for constructing a formaldehyde sensor with rapid detection and low power consumption.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.
