Abstract

The electrospinning technique is famous for its versatility and ability to construct non-woven matrix on the nano and micrometric scales. Aiming at various applications, being able to customize these structures with the combination of different polymer compositions, morphologies and also being able to add factors such as antibiotics, clays, essential oils, growth factors, among other agents, makes the technology even more attractive. Making electrospinning portable is the objective of this project. Portable systems for in situ deposition of fibrous matrices have attracted interest from the technological, textile, food and pharmaceutical sectors. From a carrier safety perspective, exploring new ideas for electrospray and electrospinning systems is a challenge. Therefore, this PIPE 1 proposes the development of a portable multifunctional electrospinning gun, aiming at the deposition of polymeric fibers on different substrates, such as metallic implants, seeds and food. Devices like these are innovative, low-cost, safe and portable, with applicability in several areas, including regenerative medicine. In STAGE 1, the methodology comprises the construction of a beta prototype, based on the development of technical and electronic drawings, the assembly of circuits, the automation of the infusion of polymeric solutions and the integration of ultraviolet light for polymer sterilization and photocuring. In STAGE 2, security tests will be carried out internally, in the 3DBS laboratory and externally, with the hiring of third parties specialized in validating devices of this type. Internal validation includes the production of membranes from the developed portable MVP and comparison with membranes produced with benchtop electrospinning technology. At each stage, the project aims for specific deliveries, referencing Technology Readiness Level (TRL) levels. Challenges include operator safety, fiber formation compared to equipment validated by startup 3DBS, system miniaturization and logistics of acquiring imported components. Seeking to contribute to global technological and economic advances, the project aims to positively impact sectors such as health, agriculture, industry and technology. The creation of an innovative and nationally competitive device positions itself as an important difference internationally. (AU)
