An organic artificial spiking neuron for in situ neuromorphic sensing and biointerfacing

open access: yesNature Electronics, 2022
An organic artificial neuron that is based on a compact nonlinear electrochemical element can operate in a liquid and responds to the concentration of biological species in its surroundings, allowing its behaviour to be modulated, for example, by ...

Photosensitive ion channels in layered MXene membranes modified with plasmonic gold nanostars and cellulose nanofibers

open access: yesNature Communications, 2023
Artificial ion channels are in demand for ionotronic devices. Here, the authors use layered MXene membranes modified with plasmonic gold nanostars and cellulose nanofibers to convert a thermal gradient into an ion current for photosensitive ion ...

A Practical Guide to Preparation and Applications of Giant Unilamellar Vesicles Formed via Centrifugation of Water-in-Oil Emulsion Droplets

open access: yesMembranes, 2023
Giant vesicles (GVs), which are closed lipid bilayer membranes with a diameter of more than 1 μm, have attracted attention not only as model cell membranes but also for the construction of artificial cells.

Fluctuations of a driven membrane in an electrolyte [PDF]

open access: yesEurophys. Lett. , 77, 18006 (2007), 2006
We develop a model for a driven cell- or artificial membrane in an electrolyte. The system is kept far from equilibrium by the application of a DC electric field or by concentration gradients, which causes ions to flow through specific ion-conducting units (representing pumps, channels or natural pores).

Artificial Signal Transduction across Membranes [PDF]

open access: yesChemBioChem, 2019
AbstractA key conundrum in the construction of an artificial cell is to simultaneously maintain a robust physical barrier to the external environment, while also providing efficient exchange of information across this barrier. Biomimicry provides a number of avenues by which such requirements might be met. Herein, we provide a brief introduction to the

Electrically controlled water permeation through graphene oxide membranes [PDF]

open access: yesNature 559, 236-240, 2018, 2018
Developing 'smart' membranes that allow precise and reversible control of molecular permeation using external stimuli would be of intense interest for many areas of science: from physics and chemistry to life-sciences. In particular, electrical control of water permeation through membranes is a long-sought objective and is of crucial importance for ...
