| Patent No. | Title of Patent | Aim | Description |
|---|---|---|---|
| US 10,898,703 B2 | MNs template and MNs prepared using the same. | Preparation of MNs template; Preparation of MNs, using a prepared template and MNs preparation method. | An MNs template includes a substrate on which a minimum of one MNs shape is projected to which at least one diamond layer is formed on the MNs surface. |
| US 2021/0008360 A1 | Adhesion membrane and MNs patch | To provide a new patch with excellent flexibility to skin, which carries an MNs array patch. | MNs provide excellent skin punctures and also stay on the skin; Provides variation in puncture property depending on the elasticity of the skin. |
| US 2021/0030975 A1 | Application for applying an MNs device to the skin | An applicator, method for application of MNs device to the skin | Applying the MNs device on the skin delivers active ingredients for treatment using applicators and methods. |
| US 10,946,180 B2 | Applicators for MNs | Description of micro projection array for MNs application | Applicator and method for applying MNs for treatment. |
| US 10,973,757 B2 | Biodegradable MNs device | To provide one or more biodegradable MNs capable of drug administration to the skin. | The invented device is embodied in MNs form for skin applications. At least one biodegradable MNs is projected from the cap with the lower surface abutted. MN projection is formed by a polymeric blend of preserved stem cell factors. |
| US2021/0046299A1 | Composite MNs array including nanostructures thereon | A composite MNs array overlays the film (consists of a plurality of nano-sized structures fabricated thereon) with MNs. | MNs array and MNs assembly and film consist of a plurality of nano-sized structures fabricated for drug delivery applications. |
| US 2021/0106520 A1 | Conductive polymer MNs arrays for electronically controlled drug release | A method that delivers a therapeutic agent, provided with an MNs array, also includes a plurality of MNs, including conductive coating disposal. | Conductive coating derived controlled therapeutic agent release by using MNs array implant in and across the dura mater to CNS of the subject. |
| US 10,987, 503 B2 | Dissolvable MNs for skin treatment | A skin treatment includes MNs application on the skin and penetration to the stratum corneum. | Polymeric MNs and their methods as a skin treatment device |
| US 10,994,111 B2 | Drug holding MNs array and manufacturing method thereof | To provide a drug-holding MNs array, where the drug is applied and held on the area of the tip of the MNs, for holding the dose capacity and prevention of drug spillage during insertion. | Technique for drug holding into MNs by step formation on MNs for quantitative dose administration |
| US 2021/0106259 A1 | The electrically functional polymer MN array | A sensor (biosensor) device comprises a polysubstrate substance structured to form MNs. | A device with electrodes, related devices, apparatus and fabrication methods, and devices use |
| US8708966B2 | MNs devices and methods of manufacture and use thereof | A method for delivering the active agent across a biological barrier | Devices with MNs are available for transporting compounds across tissue barriers and serving as microflameholders |
