| 1 | In Vivo Phenotyping for the Early Detection of Drought Stress in Tomato显示文摘Drought stress imposes a major constraint over a crop yield and can be expected to grow in importance if the climate change predicted comes about.Improved methods are needed to facilitate crop management via the prompt detection of the onset of stress.Here,we report the use of an in vivo OECT(organic electrochemical transistor)sensor,termed as bioristor,in the context of the drought response of the tomato plant.The device was integrated within the plant’s stem,thereby allowing for the continuous monitoring of the plant’s physiological status throughout its life cycle.Bioristor was able to detect changes of ion concentration in the sap upon drought,in particular,those dissolved and transported through the transpiration stream,thus efficiently detecting the occurrence of drought stress immediately after the priming of the defence responses.The bioristor’s acquired data were coupled with those obtained in a high-throughput phenotyping platform revealing the extreme complementarity of these methods to investigate the mechanisms triggered by the plant during the drought stress event. | Michela Janni Nicola Coppede Manuele Bettelli Nunzio Briglia Angelo Petrozza Stephan Summerer Filippo Vurro Donatella Danzi Francesco Cellini Nelson Marmiroli Domenico Pignone Salvatore Iannotta Andrea Zappettini | 2019 | Plant Phenomics2019，1，1： | 1 |
| 2 | Flow velocity and temperature sensing using thermosensitive fluorescent polymer seed particles in water显示文摘Particle image velocimetry(PIV)is an experimental technique that uses microscale particles as tracers to measure the velocity of a fluid flow.In this paper,we seek to extend this technique to simultaneously measure fluid temperature as well,by employing a novel class of thermosensitive polymer particles.Towards this aim,we designed a process to encapsulate highly fluorescent thermosensitive NBD-AE-co-poly(N-isopropylacrylamide)polymers into optically transparent poly(dimethylsiloxane)particles.These novel PIV particles enable direct measurement of water velocity while serving as temperature probes that increase their fluorescence intensity when the temperature rises above 32°C.To demonstrate the ability of the particles to simultaneously serve as flow tracers and temperature sensors in water,we examine the flow velocity and temperature in the wake of a heated cylinder in a cross flow.Our results indicate the possibility of extending PIV to afford the spatial and temporal resolution of fluid velocity and temperature gradients in water,with potential application to the study of convection problems from life sciences to engineering. | Filippo Cellini Sean D.Peterson Maurizio Porfiri | 2017 | International Journal of Smart and Nano Materials2017，8，4： | 0 |
