Remember the project where University of Sidney scientists used 3D printing to 
Imaging of single DNA molecules has been of particular interest as various diseases including cancer and neurological disorders, such as Alzheimer’s disease, are associated with genomic alterations, including, for example, copy-number variations (CNVs). Such a simple, field-portable and cost-effective microscopy device can be used in various clinical applications, like the detection of certain cancers (e.g., stomach, brain, etc.), nervous system disorders, or even drug resistance in infectious diseases. Furthermore, by collecting and mapping the integrated spatiotemporal data, it can provide support to health-care professionals, epidemiologists, and policy makers in tracking emerging trends and gain a better understanding of cause-effect relationships.
The extreme sensitivity of the sensors and lenses on modern smartphones, in particular the Lumia 1020, are proving ideal for an ever growing number of medical and scientific applications. While the technology is important, it is often through 3D printed accessories that scientific teams are able to make the best intended use of these powerful portable computers, so that one Start Trek dream, the replicator, is helping another one, the tricorder, get closer to reality.
