An easy-to-prepare chemosensor, 2-(4-formylphenyl)phenanthroimidazole 1, synthesized by facile one-step condensation under microwave irradiation, has been indicated to be a colorimetric and fluorometric probe for fluoride anion with good sensitivity and high selectivity. This probe shows obvious red shift and absorbance intensity changes in UV absorption(More)
Based on a unique elimination reaction prompted by the iodide ion, a novel turn-on fluorescence probe (HCy-OMe-Br) has been developed for the first time. The probe emits in the near infrared region with a large Stokes shift, and can respond rapidly to iodide with high selectivity and sensitivity.
1 Abstract— A low-dropout regulator (LDO) for the electrical stimulation of ionic electroactive polymers (iEAPs) used in subcutaneous muscle prosthesis is presented. The special requirement of the application and the characteristics of iEAPs impose several design challenges for the stimulator. In this paper, these challenges are discussed and solutions are(More)
To reduce the side effects of chemotherapy, nontoxic prodrugs activated by the tumor microenvironment are urgently required for use in cancer treatment. In this work, we developed prodrug 4 for tumor-targeting treatment and imaging of the anticancer drug release in vivo. Taking advantage of the high glutathione (GSH) concentration in cancer cells, the(More)
Hydrogen selenide (H2Se), a highly reactive Se species, is an important selenium metabolism intermediate involved in many physiological and pathological processes. This compound is of scientific interest with regard to the real-time monitoring of H2Se in living cells and in vivo to understand the anti-cancer mechanism of selenium. However, monitoring H2Se(More)

In this report, the design and implementation of a low-cost, portable and wearable pulse oximeter is presented. A pulse oximeter is a non-invasive device capable of monitoring the blood’s oxygen saturation. It has been widely used in the medical, fitness and clinical care worlds. A low-cost wearable oximeter can significantly expand its applicability. The(More)
Oxygen reduction reaction (ORR) is the cornerstone in the electrochemical energy conversion devices such as fuel cells and metal-air batteries. It remains a great challenge to develop the ORR electrocatalysts with fast kinetics and high durability. Herein, we report the synthesis of a novel metal-organic coordination networks material, prussian blue(More)
