报告一
题    目:Nanotechnology-A science with the face of Janus +An Introduction to Cranfield University and Cranfield Health
报告人:Professor Joe Lunec
时    间:11月21号14:00-16:00
地    点:研究生楼303

报告内容:
Nanotechnology, or nanotech, is the study and design of machines on the molecular and atomic level. To be considered nanotechnology, these structures must be anywhere from 1 to 100 nanometers in size. Instead of building microscopic motors and computers, researchers are interested in building superior machines atom by atom. Nanotech means that each atom of a machine is a functioning structure on its own, but when combined with other structures, these atoms work together to fulfill a larger purpose.

报告人简介:
Professor Joe Lunec is Head of Cranfield Health, Cranfield University’s newest School.Professor Lunec is a graduate in Chemistry from Queen Mary College, University of London and has a PhD and DSc in Chemical Pathology from the University of London. He is a Fellow of the Royal College of Pathologists and periodically a government advisor on Medical Toxicology issues.

报告二
题    目:Detection of [Ca2+] changes in sub-plasma membrane microdomains in a single living cell by an optical fiber-based nanobiosensor
报告人:Professor Shenqi Wang
时    间:11月21号14:00-16:00
地    点:研究生楼303

报告内容:
Ca2+-induced Ca2+ release is a general mechanism thatmost cells use to amplify Ca2+ signals. In heart cells,this mechanism is operated between voltage-gated L-type Ca2+ channels (LCCs) in the plasma membrane and Ca2+ release channels,commonly known as ryanodine receptors, in the sarcoplasmic reticulum.We show that the local Ca2+ signal produced by a single opening of an LCC, named a 'Ca2+ sparklet',can triggerabout ryanodine receptors to generate a Ca2+ spark. The coupling between LCCs and ryanodine receptors is stochastic,as judged by the exponential distribution ofthe coupling latency.

报告人简介:
Dr Shenqi Wang obtained his PhD degree from Wuhan University of Technology. After his PhD study, he spent two years as a Postdoctoral Fellow at the key laboratory of bioactive materials, Ministry of Education, Nankai University. He joined Cranfield Health as a Marie Curie Fellow(MC-IIF) in September 2010.


报告三
题    目:On/off switchable smart functional imprinted polymers +Collaborative opportunities in research and education
报告人:Professor Yi Ge
时    间:11月30号14:00-16:00
地    点:研究生楼303
报告内容:
‘On/off’-switchable catalysis by a smart enzyme-like、imprinted polymer is reported.At a relatively low temperature, this polymer was capable of vigorous catalysisfor the hydrolysisof p-nitrophenyl acetate due to its hydrophilic networks. At higher temperatures , this polymer demonstrated poor catalysis  This novel imprinted polymer employed thermosensitive poly(N-isopropylacrylamide) networks, thus enabling the switchable catalysis.

报告人简介:
Dr Ge obtained his bachelors degree in Biopharmaceutics and went on to an MPhil degree in Pharmaceutical Chemistry at Aston University. Afterwards,he moved to the University of Sheffieldfor a PhD in Chemistry.Then he joined Cranfield Health as a member of academic staff in the group of advanced sensor and smart material in 2006. He has served as the Vice-President of the International Association of Advanced Materials and the Associate Editor for
Advanced Materials Letters.

报告四
题    目:New Methods for the Preparation of Molecularly Imprinted Polymer-Based Nanoparticles, Fluorescent Sensors and Electrochemical Sensors
报告人:Professor Mike Whitcombe
时    间:11月30号14:00-16:00
地    点:研究生楼303

报告内容:
A novel approach to the introduction of recognition site functionality into highly cross-linked polymeric matrices via molecular imprinting has been developed for compounds with single (or multiple, spatially separated) hydroxyl groups. This new methodology relies on the use of the 4-vinylphenyl carbonate ester which functions as a covalently bound template monomer but is easily and efficiently cleaved hydrolytically with the loss of CO2.This results in the formation of a noncovalent recognition site,bearing a phenolic residue, capable of interacting with the ligand (template) through hydrogen bonding.

报告人简介:
Mike obtained a BA in Chemistry from Oxford University and a PhD from London University on photoresist chemistry. He spent four years as a post-doctoral fellow at the Polymer Science Centre at The University of Reading working on photoactive liquid crystalline polymers and polymers for non-linear optics before joining the Institute of Food Research at Reading to work on imprinted polymers in 1991, moving to Norwich in 1999. He joined Cranfield University as a lecturer in 200
