Transportation of calcium ions through chemically modified nanochannels in a polymeric membrane
Abstract Synthetic ion channels fabricated on PET membrane are gaining considerable attention in the field of bioinspired devices. These bioinspired devices can mimic the gating functions of biological ion channels. In the present study, the synthesized nanochannels in the polymer membrane have been...

520 | |a Abstract Synthetic ion channels fabricated on PET membrane are gaining considerable attention in the field of bioinspired devices. These bioinspired devices can mimic the gating functions of biological ion channels. In the present study, the synthesized nanochannels in the polymer membrane have been used for the transportation of the calcium ions through them under the influence of applied voltage(s). Ion irradiation followed by chemical etching has been used for the fabrication of the ion channels. Changes due to ion irradiation and chemical etching (with different etching rates) have been investigated by field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) and X-ray diffraction techniques. The porous membrane obtained by etching for longer duration has been used for ions’ selection and calcium ions’ transportation. Aqueous calcium perchlorate electrolyte (with different concentrations), similar to the myocyte, has been used. The multiple-ion channels present in the membrane respond simultaneously and the resultant current is due to the transportation of the ions as an outcome of their interaction with the charges ($ COO^{−} $) present on the channelś’ walls. The transportation rate of cation(s) and the anion(s) accumulated outside the membrane (and hence the nanochannels) is reflected in the current behaviour. Effect of concentration as well as electrical gradient on the ion transportation has been studied. Ion current rectification behaviour of these voltage-gated calcium nanochannels with different anions has also been studied. | ||

These bioinspired devices can mimic the gating functions of biological ion channels. In the present study, the synthesized nanochannels in the polymer membrane have been used for the transportation of the calcium ions through them under the influence of applied voltage(s). Ion irradiation followed by chemical etching has been used for the fabrication of the ion channels. Changes due to ion irradiation and chemical etching (with different etching rates) have been investigated by field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) and X-ray diffraction techniques. The porous membrane obtained by etching for longer duration has been used for ions’ selection and calcium ions’ transportation. Aqueous calcium perchlorate electrolyte (with different concentrations), similar to the myocyte, has been used. The multiple-ion channels present in the membrane respond simultaneously and the resultant current is due to the transportation of the ions as an outcome of their interaction with the charges ($ COO^{−} $) present on the channelś’ walls. The transportation rate of cation(s) and the anion(s) accumulated outside the membrane (and hence the nanochannels) is reflected in the current behaviour. Effect of concentration as well as electrical gradient on the ion transportation has been studied. Ion current rectification behaviour of these voltage-gated calcium nanochannels with different anions has also been studied.

These bioinspired devices can mimic the gating functions of biological ion channels. In the present study, the synthesized nanochannels in the polymer membrane have been used for the transportation of the calcium ions through them under the influence of applied voltage(s). Ion irradiation followed by chemical etching has been used for the fabrication of the ion channels. Changes due to ion irradiation and chemical etching (with different etching rates) have been investigated by field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) and X-ray diffraction techniques. The porous membrane obtained by etching for longer duration has been used for ions’ selection and calcium ions’ transportation. Aqueous calcium perchlorate electrolyte (with different concentrations), similar to the myocyte, has been used. The multiple-ion channels present in the membrane respond simultaneously and the resultant current is due to the transportation of the ions as an outcome of their interaction with the charges ($ COO^{−} $) present on the channelś’ walls. The transportation rate of cation(s) and the anion(s) accumulated outside the membrane (and hence the nanochannels) is reflected in the current behaviour. Effect of concentration as well as electrical gradient on the ion transportation has been studied. Ion current rectification behaviour of these voltage-gated calcium nanochannels with different anions has also been studied.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ion tracks</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Calcium ion channels</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bioinspired devices</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Khurana, Shilpa</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chandra, Amita</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Ionics</subfield><subfield code="d">Berlin : Springer, 1995</subfield><subfield code="g">28(2022), 3 vom: 10.

Transportation of calcium ions through chemically modified nanochannels in a polymeric membrane |
abstract |
Abstract Synthetic ion channels fabricated on PET membrane are gaining considerable attention in the field of bioinspired devices. These bioinspired devices can mimic the gating functions of biological ion channels. In the present study, the synthesized nanochannels in the polymer membrane have been used for the transportation of the calcium ions through them under the influence of applied voltage(s). Ion irradiation followed by chemical etching has been used for the fabrication of the ion channels. Changes due to ion irradiation and chemical etching (with different etching rates) have been investigated by field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) and X-ray diffraction techniques. The porous membrane obtained by etching for longer duration has been used for ions’ selection and calcium ions’ transportation. Aqueous calcium perchlorate electrolyte (with different concentrations), similar to the myocyte, has been used. The multiple-ion channels present in the membrane respond simultaneously and the resultant current is due to the transportation of the ions as an outcome of their interaction with the charges ($ COO^{−} $) present on the channelś’ walls. The transportation rate of cation(s) and the anion(s) accumulated outside the membrane (and hence the nanochannels) is reflected in the current behaviour. Effect of concentration as well as electrical gradient on the ion transportation has been studied. Ion current rectification behaviour of these voltage-gated calcium nanochannels with different anions has also been studied. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021 |
