Microneedles, currently a hot topic in various medical device and bioengineering fields, can be used for drug delivery or diagnostics. One of the best ways to produce them is the multi-photon polymerization technique which enables the production of precise and firm microneedles. Even more complex shapes of polymeric needles can be obtained by maintaining the high sharpness of the needle tips. Various polymeric materials can be used for microneedle fabrication depending on the exact application. In most cases, the structures can easily be replicated by using various molding techniques.
