Cell-Imprinted Substrates Modulate Differentiation, Redifferentiation, and Transdifferentiation

Philippe Renaud, Arnaud Bertsch, Morteza Mahmoudi, Shahin Bonakdar, Leila Montazeri, Mojtaba Taghipoor, Omid Mashinchian

Differentiation of stem cells into mature cells through the use of physical approaches is of great interest. Here, we prepared smart nanoenvironments by cell-imprinted substrates based on chondrocytes, tenocytes, and semifibroblasts as templates and demons ...

Thermal gate, a new tool for ionic transport control inside nanochannels

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

Transport of ionic species solvated in electrolytes depends on temperature. This dependence is much stronger in nanofluidics than large scale since the surface charge also varies with temperature. In this work, we introduce a new tool for the modulation of ...

An improved model for predicting electrical conductance in nanochannels

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

Nanochannel conductance measurements are commonly performed to characterize nanofluidic devices Theoretical analysis and experimental investigations imply that the nanochannel conductance does not follow the macro-scale models. It is generally accepted tha ...

Investigation of the thermal effects in nanofluidic transport and their application in gating

Mojtaba Taghipoor

Scaling down to nanometer size fluidic conduits has opened a new window into the world of sensing and manipulation of nanoscale species. Thousands of publications and hundreds of patents in this field are only a starting point for exploring and manipulatin ...

Thermal control of ionic transport and fluid flow in nanofluidic channels

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

In this work, we report a nanofluidic gating mechanism that uses the thermal effect for modulating the ionic transport inside nanofluidic channels. The control of the ionic transport inside a nanochannel is demonstrated using electrical conductivity. A the ...

Temperature Sensitivity of Nanochannel Electrical Conductance

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

Electrical measurement is a widely used technique for the characterization of nanofluidic devices. The electrical conductivity of electrolytes is known to be dependent on temperature. However, the similarity of the temperature sensitivity of the electrical ...

Microfluidic synthesis of chitosan-based nanoparticles for fuel cell applications

Philippe Renaud, Arnaud Bertsch, Fatemeh Sadat Majedi, Mohammad Mahdi Hasani-Sadrabadi, Mojtaba Taghipoor

A microfluidic platform is developed for the synthesis of monodisperse, 100 nm, chitosan based nanoparticles using nanogelation with ATP. The resulting nanoparticles tuned and enhanced transport and electrochemical properties of Nafion based nanocomposite ...
