A collaborative research team hailing from Canada and the United States has unveiled a groundbreaking high-resolution 3D printing technology. This innovation ingeniously harnesses the proboscis of female mosquitoes, repurposing it as a printing nozzle. The conventional production process for ultrafine nozzles, which are commercially available, is intricate, expensive, and poses environmental concerns along with potential health hazards.

In stark contrast, the mosquito's proboscis has undergone millions of years of evolution, culminating in a natural micro-needle structure that is both efficient and precise. The research team meticulously isolated and secured the mosquito's suction tube onto the tip of a dispenser, thereby crafting a bio-nozzle. This novel nozzle is not only robust enough to withstand high pressure but also boasts a printing precision that is roughly double that of commercial nozzles.

The team has already leveraged this technology to fabricate a diverse array of structures. This technology's prowess lies not only in its ability to manufacture ultra-fine structures but also in the fact that the nozzles are biodegradable and can be reused. Drawing inspiration from the utilization of biological structures as engineering components, this technology opens up a vast expanse of possibilities in the realms of biomedicine and precision electronics.
