An important hurdle to the democratisation of cell therapies and cell-based in vitro models remains our limited ability to scale up and automate cell manufacturing and processing. Whilst solid and hydrogel microcarriers and magnetic microparticles have shown some promise to tackle this pitfall, they remain difficult to process and separate from cell products, lead to potential contamination of the cell mass generated and are associated with high costs. The design of affordable, scalable and regulatory-ready platforms for the culture and processing of adherent cells, yet by-passing the reliance on solid substrates and microcarriers, remains essential for cell manufacturing and will have an important impact on the sustained growth of associated biotech markets. To bypass the contamination of cell products with microplastics or particles, simplify bioprocessing and reduce associated costs, bioemulsions have recently been proposed as attractive alternatives. Although their performance has been demonstrated in a growing number of cases, current protein and polymer nanosheet technologies rely on protein and materials that present a risk for regulatory compliance, for applications in regenerative medicine (including for cell implantation).

细胞疗法和基于细胞的体外模型民主化的重要障碍仍然是我们扩大和自动化细胞制造和处理能力的有限能力。尽管固体和水凝胶微载体和磁性微粒已显示出有望解决此陷阱的希望，但它们仍然很难处理并与细胞产物分离，从而导致可能产生的细胞质量污染，并与高成本相关。负担得起的，可扩展的和适合监管的平台用于培养和处理粘附细胞的培养和处理，但通过依赖对固体基板和微载体的依赖对于细胞制造仍然至关重要，并且将对相关生物技术市场的持续增长产生重要影响。为了绕过具有微塑料或颗粒的细胞产品的污染，简化生物处理并降低相关成本，最近提出了生物乳剂作为有吸引力的替代品。尽管在越来越多的病例中证明了它们的性能，但当前的蛋白质和聚合物纳米片技术依赖于蛋白质和材料具有调节性依从性风险的材料，用于再生医学（包括细胞植入）。
