Abstract
En 中文
Biological olfactory systems are highly sensitive and selective, often outperforming engineered chemical sensors in highly complex and dynamic environments. As a result, there is much interest in using biological systems to build sensors. However, approaches to read-out information from biological systems, especially neural signals, tend to be suboptimal due to the number of electrodes that can be used and where these can be placed. Here we aim to overcome this suboptimality in neural information read-out by using a nano-enabled neuromodulation strategy to augment insect olfaction-based chemical sensors. By harnessing the photothermal properties of nanostructures and releasing a select neuromodulator on demand, we show that the odour-evoked response from the interrogated regions of the insect olfactory system can not only be enhanced but can also improve odour identification. Insects have been shown to have the ability to detect different chemical agents. Here, the authors present a nanomaterial-assisted neuromodulation strategy to augment the chemosensory abilities of insects via photothermal effect and on-demand neurotransmitter release from cargo-loaded nanovehicles to augment natural sensory function.
