Llamado a Beca Postdoctoral CONICET 2022<\/strong><\/h3>\n

Tema: Dispositivos Nanoflu\u00eddicos Basados en Nanoporos de Estado S\u00f3lido \u2013 Dise\u00f1o, Construcci\u00f3n y Aplicaciones en Biosensado y Conversi\u00f3n de Energ\u00eda.<\/strong><\/p>\n

Descripci\u00f3n del Proyecto:<\/strong>
\nEl transporte de iones a trav\u00e9s de canales de tama\u00f1o nanom\u00e9trico depende de las propiedades f\u00edsicas y qu\u00edmicas de sus paredes. Utilizando canales de tama\u00f1o, forma y recubrimientos superficiales adecuados es posible regular el transporte de iones a trav\u00e9s de las membranas para producir sensores de especies qu\u00edmicas o controlar el flujo de corriente i\u00f3nica modificando variables externas. El control del flujo selectivo de iones es esencial en el desarrollo de generadores de energ\u00eda osm\u00f3tica, que permiten obtener energ\u00eda el\u00e9ctrica a partir de dos fuentes de agua de diferente concentraci\u00f3n salina.<\/p>\n

Por otro lado, la integraci\u00f3n de diversos elementos de reconocimiento como pol\u00edmeros, enzimas, apt\u00e1meros y anticuerpos a las paredes de los canales permite utilizar las medidas de corriente i\u00f3nica para la determinaci\u00f3n de diferentes especies en soluci\u00f3n alcanzando bajos l\u00edmites de detecci\u00f3n y elevada especificidad de sensado.
\nEn los \u00faltimos a\u00f1os nuestro laboratorio ha trabajado extensamente en el desarrollo de nanosensores ultrasensibles y nanomembranas para conversi\u00f3n de energ\u00eda osm\u00f3tica utilizando estas arquitecturas nanoflu\u00eddicas como plataformas de construcci\u00f3n, fabricando membranas con un \u00fanico canal o miles de canales por cent\u00edmetro cuadrado.
\nEn este marco de trabajo nos encontramos buscando un\/a candidato\/a para presentarse al pr\u00f3ximo llamado para Beca Posdoctoral de CONICET, que tendr\u00e1 lugar del\u00a014\/02\/2022<\/strong>\u00a0al\u00a04\/03\/2022<\/strong>.<\/p>\n

Inicio de actividades:<\/strong> 01\/08\/2022.<\/strong> La duraci\u00f3n de la beca es de treinta y seis (36) meses.<\/p>\n

Requisito del becario\/a:\u00a0<\/strong>tener t\u00edtulo de Doctor\/a en Qu\u00edmica, F\u00edsica, Ingenier\u00eda, Materiales, Biotecnolog\u00eda o tesis aprobada antes del\u00a031\/07\/2022<\/strong>. Enviar CV actualizado y carta manifestando las razones por las que posee inter\u00e9s en la propuesta, antes del 14\/02\/2022.<\/p>\n
