Microneedle array patches for skin hyperthermia and enhanced intradermal drug delivery
Microneedles (MN) arrays are micron-size needle arrays with length generally ranging between 50 μm and 2 mm. When applied to the skin surface, they pierce the stratum corneum creating micropores that can enhance the delivery of drugs into the viable skin layers. MN arrays offer great advantages for …

Optimisation of microneedle array design for microneedle mediated iontophoretic transdermal drug delivery
… recently been suggested that a combination of microneedle (MN) and iontophoresis (ITP) technologies may broaden the range of macromolecules that may be successfully delivered across the skin, with the added benefit of precise electronic control over the rate of transdermal drug delivery. MNs …

InsulPatch: A Slim, Powerless Microfluidic Patch-Pump for Insulin Delivery
… photolithography and replica molding, and a microneedle array fabricated using 3D printing. The microfluidic pump is used to drive the fluid flow powered by pressurized air or the user’s pulse, and the microneedle array is used to inject the fluid through the skin painlessly. Using …

Polymer substrates with microneedles for epidermis injection
… macroneedles. A spectic substrate system with microneedles can prevent irflammation or tear of the epidermis but still puncture for cargo release. Depending on the substrate contact surface area, a larger microneedle array can be utilized, for a higher success rate of release beyond individual …

The development of a minimally invasive glucose sensing system
… diabetic patients. The device will consist of an array of micro-needles that penetrates only the stratum corneum layer of the skin and tests glucose levels in the interstitial fluid (IF). This device does not reach the depth of the nerve endings, and so provides a painless means of glucose …
