A method for locally introducing a light emitter or a plasmonic element into a light guide is provided. The method () comprising the acts of: applying () a printing head () to a surface () of the light guide (), the printing head () comprising an insertion portion () comprising the light emitter () or the plasmonic element and a heating element (), heating () the heating element () such that a portion () of the surface () of the light guide () is locally heated, pressing () the printing head () into the light guide () such that at least a portion () of the insertion portion () is inserted into the light guide (), introducing () the light emitter () or the plasmonic element () into the light guide () via the insertion portion (). A printing head () for locally introducing a light emitter () or a plasmonic element () into a light guide () is also provided. A light guide () comprising a light emitter () or a plasmonic element () introduced into the light guide () by use of the method () or the printing head () is further provided.

The present invention relates to an optical fiber for use in a system for detection of one or more compounds in a fluid. The optical fiber () comprising at least two binding portions () separated from each other along the longitudinal direction () of the optical fiber (), wherein each of the at least two binding portions () comprises a plasmonic structure () and/or a SERS structure (), and a binding material () for binding of one or more compounds, wherein at least two binding portions () are arranged for binding the same compound or compounds, wherein the optical fiber () is arranged for receiving light and transmitting light to each of the at least two binding portions, wherein each of the at least two binding portions () is arranged such that light transmitted through that binding portion () without bound compound is different compared to light transmitted through that binding portion () with bound compound, or light reflected back from that binding portion () without bound compound is different compared to light reflected back from that binding portion () with bound compound. The present invention further relates to a system () for detection of one or more compounds in a fluid () and an optical fiber () for use in such a system () and a method () using the system ().
