Qun-Dong Shen, Professor of Chemistry

Welcome to The Shen Research Group in School of Chemistry and Chemical Engineering at Nanjing University.

Research Interests

Ferroelectric polymer as bio-inspired  photodetector for artificial retina. Photo-isomerization of a dye embedded the ferroelectric membrane leads to polarization change under visible light. High sensitivity, color recognition, transient response, 3D visual detection, and high resolution can be achieved in photodetector array. The signal is readily transmitted to neuron.  Adv. Mater. (2016)

Ferroelectric polymer free-standing nano-dot arrays with ultrahigh data storage density fabricated using nano-imprinting. Nanometer electronic features can be written directly in two dimensions using piezoresponse force microscopy probe based technology. Adv. Funct. Mater. (2013)

A wearable transducer for non-invasive and dynamic diagnosis of cardiovascular system by ferroelectric polymer. The transducer has low power consumption and is applicable to remote detecting warning signals of heart attacks and assessing efficiency of heart drugs. Adv. Funct. Mater.  (2016)

Conjugated polymers as bright fluorescent labels for imaging of biological cells and tissues. Based on the fluorescence signal modulation of the polymers in response to the analytes, it has driven interest in high-sensitive and rapid-response fluorescence biosensors.

Light-activated conjugated polymer hypoxia- esponsive drug-delivery vehicle. This nanocarrier can be activated by photo-irradiation, producing singlet oxygen (1O2) and inducing hypoxia to promote release of its cargo inside tumor cells for enhanced anticancer efficacy. Adv. Mater. (2016)
