The importance of antimicrobial membranes has significantly grown during the recent COVID pandemic era. Nanofibrous antimicrobial membranes have seen novel applications in biomedicine, such as face masks against viral threats or wound dressings used in chronic patient care. Composite electrospun nanofiber meshes are convenient to use as antimicrobial membranes. At present, the lack of automated, inline quality control limits both the pilot and large scale production of multi-material multilayer composite membranes. The alternative, manual re-calibration greatly limits production throughput and thus commercial viability. The goal of this R&D activity is to create technology for scalable inline quality control of electrospun nanofiber meshes. Using cognitive electronics, the system will be capable of continuous multiparameter monitoring and electrospinning process control to maintain optimal product quality and distribution.
The overall objective of the original CHIRALFORCE project is to demonstrate enantiomer separation in a compact, on-chip, photonic platform that is fabricated using standard silicon-based technology. This CHIRALFORCE2 hop-on project enhances the original project by providing automated in-line platform for the analysis of chiral separation for this CHIRALFORCE photonic chip.
Separation of enantiomers from mixtures is essential, especially in early phase drug discovery processes when many mixtures need to be separated. CHIRALFORCE aims to revolutionize the field of chiral chemistry by introducing a radically new strategy for separating enantiomers by using chiral optical forces in silicon-based photonic integrated waveguides to separate enantiomers. The successful implementation of CHIRALFORCE project (development of separator chip) relies on fast and accurate feedback on the enantiomer separation. However, current state-of-the art technologies for checking the enantiomer separation: e.g. circular dichroism (CD) spectroscopy or High-Performance Liquid Chromatography (HPLC) lack off-the shelf capabilities for rapid in-line separation monitoring that is needed in CHIRALFORCE project. CHIRALFORCE2 addresses this need by providing a platform for in-line monitoring of the chiral separation down-stream from the CHIRALFORCE separator chip. We use interdisciplinary approach combining automation, electronics, optics and IT disciplines. The monitoring of in-line chiral separation will be achieved by CD-spectrometry or absorbance detection depending on the microfluidic and optical requirements from CHIRALFORCE project. Both scenarios are supported by designated software for the signal analysis and feedback.
