Both Macro needles and Microneedles have had modernized designs inspired by the mosquito proboscis to enhance insertion for medical use. Though they have similar functions, there are some key factors that differentiate macro needles from microneedles. |

[[Microneedles]] are micron-scaled needles that are typically used in an array in a patch. The height of the needle typically ranges from 25 to 2500 μm and pierces through the outermost layer of the epidermis of the skin. They are most well known for creating micropores where the drug can be passively absorbed with limited violation to the body{{Citation |title=Microneedles |date=2026-04-15 |work=Wikipedia |url=https://en.wikipedia.org/w/index.php?title=Microneedles&oldid=1349100615 |access-date=2026-04-21 |language=en}}. |

Microneedles can have different characteristics based on their purpose of application. The most common are solid, hollow, coated, and dissolving needles. Each method has different features that can support different techniques. Overall, they are less destructive and slow-moving methods of injecting drugs. |

Macro needles normally used in vaccines and injections. They are larger in size and penetrate around ⅝ to 1.5 inches through the body for a typical vaccine{{Cite web |last=CDC |date=2024-11-21 |title=Vaccine Administration |url=https://www.cdc.gov/vaccines/hcp/imz-best-practices/vaccine-administration.html |access-date=2026-04-17 |website=Vaccines & Immunizations |language=en-us}}. They are helpful for administering larger volumes of drugs into the body quickly. Hypodermic needles are hollow needles typically made of stainless steel and are most common for administering drugs. |
