“…The most common techniques, such as SLA and FDM, produce components with surface roughness that disperse too much light to be effective optical couplers. The technique that does not suffer this problem of resolution is two-photon polymerization, and there are many examples of 2PP being used to print optical components, like multi-lens objectives and free-form coupling elements (Figure a) that will have many applications for analytical sensing. − The excessive time scale of 2PP manufacturing, ∼100 days for 1 mm 3 , means that it is limited to microstructured components, however, and may have difficulty becoming a widespread technique for academic laboratories who want to prototype macro-scale instrumentation.…”

The recent explosion of 3D printing applications in scientific literature has expanded the speed and effectiveness of analytical technological development. 3D printing allows for manufacture that is simply designed in software and printed in house with nearly no constraints on geometry, and analytical methodologies can thus be prototyped and optimized with little difficulty. The versatility of methods and materials available allows the analytical chemist or biologist to fine tune both the structural and functional portions of their apparatus. This flexibility has more recently extended to optical-based bioanalysis, with higher resolution techniques and new printing materials opening the door for a wider variety of optical components, plasmonic surfaces, optical interfaces and biomimetic systems that can be made in lab. There have been discussions and reviews of various aspects of 3D printing technologies in analytical chemistry: this review highlights recent literature and trends in their applications to optical sensing and bioanalysis.
