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 Polymers for Memories and Energy Utilization

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)

Flexible nonvolatile memory with storage density of tens to hundreds Gbit/in2 through manipulating electric polarization state of ferroelectric polymer by tiny force (less than 100nN). Details

Conjugated Polymers for Biological Applications

Water-soluble 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.

A light-activated conjugated polymer hypoxia-responsive 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)

Conjugated polymer nanoparticles for sensing  and in vivo fluorescence imaging of dopamine, a neurotransmitter that plays a key role in motivation, reward, habit learning, and motor control. Details
