The Advantages of Exenatide Microneedle Patch Preparation Technology
The backing layer is prepared with the same polymer solution as the needle tip, and polyvinyl alcohol is used as the backing film-forming material to support the microneedle fractions, so that the backing layer has a tight bond with the microneedle tip, and the backing film and the needle tip can be consistently detached from the mold when the film is uncovered, without the problem of process ...

3D Printing Technology for Microneedle Preparation
Microneedles have gained significant attention in recent years for their potential in drug delivery applications. These tiny needles, typically measuring less than 1 mm in length, can painlessly penetrate the skin and deliver drugs in a precise and controlled manner. One of the key challenges in microneedle fabrication is achieving high precision and uniformity in needle design, and this is where ...

Exploring the Origins and Categorization of Microneedles
Microneedles (MN) is a new type of physical permeability-enhancing technology. It consists of multiple micron-scale fine needle tips connected to the base in an array. The needle body is generally 10-2000 microns high and 10-50 microns wide. The length, size and shape of the microneedles can be individually designed according to the needs of the application. When the microneedle delivers the ...

3 Essential Suture Tools
Medication suture dates several centuries ago, but it has improved with time. Surgical knots have played an essential role in medication and are some of the practices taught since the 15th and 16th centuries. It was an art form during the early days, and the practice was trained under a secrecy pledge. Modern medicine education teaches the proper application of knots from a scientific view, and ...

Technical Hints and Tips for Optimal Performance of your Loeser Osmometer
General function and description: The sample (serum, blood, urine or any other aqueous solution) is filled in a plastic sample tube and cooled via a Peltier element. These are semiconductor devices, which become cold on one side and warm on the other when electrical current flows through. The cold side cools the sample whilst the heat from the warm side dissipates into the air by convection. ...

Troubleshooting injection volume variation in the Concurrent Solvent Recondensation – Large Volume Sample Injection Technique
I’ve started receiving a number of questions about the large volume injection technique called Concurrent Solvent Recondensation – Large Volume Sample Injection. Most recently, a question came through the Tech Service group about injection volume variation. I had encountered a similar problem when working on the 50 µL injection for the combined 1,4-Dioxane and Nitrosamines (EPA ...
