报告摘要：
Plasmonic biosensors are considered to be highly promising for the development of simple, portable, sensitive, on-chip biodiagnostics for resource-limited settings. While there has been a tremendous progress in the rational design of plasmonic nanotransducers with high sensitivity and the development of hand-held read-out devices, the translation of these biosensors to resource-limited settings is hindered by the poor thermal, chemical and temporal stability of biorecognition elements. Degradation of the sensitive reagents and biodiagnostic chips compromises analytical validity, preventing accurate and timely diagnosis. In this talk, I will present the design and implementation of plasmonic biosensors that rely on artificial antibodies as recognition elements. This approach overcomes the poor stability of existing plasmonic biosensors and takes them closer to real-world applications in resource-limited settings.
In the second part of the talk, I will discuss the recent advances in the design and fabrication of skin-interfaced wearable medical devices capable of continuously measuring and wirelessly transmitting biophysical and biochemical information. These novel bioelectronic systems are expected to revolutionize healthcare by improving outcomes and reducing costs, as they become integral parts of modern, connected medical infrastructure. I will show that large-area, skin-like electrical interfaces enable, via advanced pattern recognition algorithms, real-time control of robotic prosthesis. These platforms are also magnetic resonance imaging (MRI)-compatible, thereby allowing for the simultaneous measurements of electroencephalography (EEG) and functional MRI. Finally, I will discuss my future research efforts in materials, wearable and implantable biomedical devices to facilitate accurate disease diagnosis and personalized medicine.
