Microneedles are an effective method for drug delivery that allows the needle portion to penetrate the skin barrier, enhancing drug permeation. However, traditional methods for preparing microneedles require time and specialized molds, making them very labor-intensive. By utilizing 3D printing technology, it is expected to significantly reduce working time, allow customization of shapes and sizes, and revolutionize the manufacturing process of microneedles. However, particularly when using water as the main solvent, the solubility of drugs in the resin for printing poses a challenge. In this webinar, Professor Lamprou will present examples of microneedle manufacturing (solid, dissolving, hollow, etc.) using our light-based bio 3D printer, 'Lumen X.'

3D printing of organ models is widely considered as an alternative to animal testing, but many of these models contain animal-derived components. This not only leads to harm to animals but also contradicts the efforts to improve the quality of science by using human organ models. In this webinar, Professor Jens Kurreck from the Technical University of Berlin will introduce his work on a xenofree liver model. This model adapts cells to FBS-free media, does not use any animal-derived materials in cell culture, and the bioink does not contain animal components such as Matrigel, collagen, or gelatin. (Starts at 10 PM Japan time, language: English) 【Recommended for】 - Those considering cell culture without any animal-derived components - Those interested in toxicity evaluation of liver models - Those looking for alternatives to Matrigel 【Date and Time】April 16, 2024 (Tuesday) 22:00-23:00 (Japan time) 【Venue】Online event *Recording available 【Speaker】Professor Jens Kurreck, Technical University of Berlin (TUB) 【Participation Fee】Free, prior registration required
