Effective intracellular delivery methods are crucial for research and therapies. This review assesses current and emerging techniques, highlighting micro-/nanotechnology and combined approaches to overcome limitations in cell delivery systems.
Area of Science:
- Biotechnology
- Cell Biology
- Bioengineering
Background:
- Intracellular delivery of cargo molecules is a major challenge in biological research and therapeutic development.
- Established physical methods like microinjection, electroporation, and sonoporation have limitations in efficacy, scalability, and flexibility.
- Emerging techniques and advancements are needed to overcome existing barriers in cargo delivery.
Purpose of the Study:
- To review and critically assess established and emerging physical methods for intracellular delivery.
- To evaluate these methods based on treatment efficacy, scalability, automation potential, and flexibility.
- To emphasize strategies involving micro-/nanotechnology and combined modalities for improved delivery systems.
Main Methods:
- Review of established physical delivery methods (microinjection, electroporation, sonoporation).
- Discussion of emerging techniques (magnetofection, optoinjection, combined modalities).
- Critical assessment of applicability, limitations, efficacy, scalability, automation, and multiplexing potential across various platforms (in vitro, ex vivo, in vivo).
Main Results:
- Existing delivery techniques often fall short in key criteria such as efficacy, scalability, automation, or flexibility.
- Micro-/nanotechnology integration and synergistic coupling of complementary methods show promise for enhancing performance.
