Concatenated logic functions using nanofluidic diodes with all-electrical inputs and outputs

Gómez Lozano, Vicente; Ramirez Hoyos, Patricio; Cervera, Javier; Ali, Mubarak; Nasir, Saima; Ensinger, Wolfgang; Mafé, Salvador (Elsevier, 2018)

[EN] Nanopore-based logical schemes in ionic solutions typically involve single gates and chemical inputs. The design of computer-like functions requires the consecutive concatenation of several gates and the use of ...
Lithium Ion Recognition with Nanofluidic Diodes through Host-Guest Complexation in Confined Geometries

Ali, Mubarak; Ahmed, Ishtiaq; Ramirez Hoyos, Patricio; Nasir, Saima; Mafé, Salvador; Niemeyer, Christof; Ensinger, Wolfgang (American Chemical Society, 2018)

[EN] The lithium ion recognition is receiving significant attention because of its application in pharmaceuticals, lubricants and, especially, in energy technology. We present a nanofluidic device for specific lithium ion ...
Logic Functions with Stimuli-Responsive Single Nanopores

Ramirez Hoyos, Patricio; Cervera Montesinos, Javier; Ali, Mubarak; Ensinger, Wolfgang; Mafé, Salvador (John Wiley & Sons, 2014)

[EN] We present the concept of logic functions based on a single stimuli-responsive nanopore and analyze its potential for electrochemical transducers and actuators. The responsive molecules at the surface of the polymeric ...
Nanoparticle-induced rectification in a single cylindrical nanopore: Net currents from zero time-average potentials

Ali, Mubarak; Ramirez Hoyos, Patricio; Nasir, Saima; Nguyen, Quoc-Hung; Ensinger, Wolfgang; Mafé, Salvador (American Institute of Physics (AIP), 2014-01-27)

Rectification in nanopores is usually achieved by a fixed asymmetry in the pore geometry and charge distribution. We show here that nanoparticle blocking of a cylindrical pore induces rectifying properties that can support ...
Nanopore charge inversion and current-voltage curves in mixtures of asymmetric electrolytes

Ramirez Hoyos, Patricio; Manzanares, José Antonio; Cervera Montesinos, Javier; Gómez Lozano, Vicente; Ali, Mubarak; Pause, Isabelle; Ensinger, Wolfgang; Mafé, Salvador (Elsevier, 2018)

[EN] We consider the screening of the negative charges (carboxylic acid groups) fixed on the surface of a conical-shaped track-etched nanopore by divalent magnesium (Mg2+) and trivalent lanthanum (La3+). The experimental ...
Optimizing Energy Transduction of Fluctuating Signals with Nanofluidic Diodes and Load Capacitors

Ramirez Hoyos, Patricio; Cervera Montesinos, Javier; Gómez Lozano, Vicente; Ali, Mubarak; Nasir, Saima; Ensinger, Wolfgang; Mafé, Salvador (John Wiley & Sons, 2018)

[EN] The design and experimental implementation of hybrid circuits is considered allowing charge transfer and energy conversion between nanofluidic diodes in aqueous ionic solutions and conventional electronic elements ...
Protein diffusion through charged nanopores with different radii at low ionic strength

Stroeve, Pieter; Rahman, Masoud; Naidu, Lekkala Dev; Chu, Gilbert; Mahmoudi, Morteza; Ramirez Hoyos, Patricio; Mafé, Salvador (Royal Society of Chemistry, 2014-10-21)

[EN] The diffusion of two similar molecular weight proteins, bovine serum albumin (BSA) and bovine haemoglobin (BHb), through nanoporous charged membranes with a wide range of pore radii is studied at low ionic strength. ...
