Abstract
One aspect of the present invention relates to a method of fabricating a chemically active fibre device (1) by thermal drawing. The method comprises the steps of providing a preform, the preform comprising a support element (3) at least partially made of a first polymeric material; and carrying out a thermal drawing process of the preform to produce a thermally drawn fibre. The preform comprises one or more chemically active agents and/or biological materials configured to react with a fluid sample when the one or more chemically active agents and/or biological materials are in contact with the fluid sample. In this manner miniaturised lab-in-fibre devices can be fabricated.

A method of fabricating a chemically active fibre device by thermal drawing, the method comprising the steps of:
- providing a preform, the preform comprising a support element at least partially made of a first polymeric material;
- and
- carrying out a thermal drawing process of the preform to produce a thermally drawn fibre,
- wherein the preform comprises one or more chemically active agents and/or biological materials configured to react with a fluid sample when the one or more chemically active agents and/or biological materials are in contact with the fluid sample, and wherein the one or more chemically active agents and/or biological materials remain active after the thermal drawing process.
A thermally drawn chemically active fibre device for sensing a fluid sample, the chemically active fibre device comprising:
- a thermally drawable support element at least partially made of a first polymeric material;
- and one or more chemically active agents and/or biological materials configured to react with the fluid sample when the one or more biochemically active agents and/or biological materials are in contact with the fluid sample at least after the support element and the one or more chemically active agents and/or biological materials have undergone a thermal drawing process.
