High-throughput cell optoporation system based on Au nanoparticle layers mediated by resonant irradiation for precise and controllable gene delivery. Sci Rep 2024; 14:3044. [PMID: 38321124 PMCID: PMC10847436 DOI: 10.1038/s41598-024-53126-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 01/29/2024] [Indexed: 02/08/2024] Open
Abstract
The development of approaches based on genetically modified cells is accompanied by a constant intensive search for new effective and safe delivery systems and the study of existing ones. Recently, we developed a new plasmonic nanoparticle layers-mediated optoporation system that can be proposed for precisely controlled, high-performance laser transfection compatible with broad types of cells and delivered objects of interest. The main goal of the present study is to demonstrate the broad possibilities and advantages of our system for optoporation of several mammalian cells, classified as "easy-to-transfect" cells, namely HeLa and CHO lines, and "hard-to-transfect" cells, namely A431 and RAW 264.7 cells. We show the efficient delivery of various sized cargo molecules: from small molecular dyes propidium iodide (PI) with molecular mass 700 Da, control plasmids (3-10 kb) to fluorophore-labeled dextranes with masses ranging from 10 kDa up to 100 kDa. The performance of optoporation was investigated for two types of laser sources, 800-nm continuous-wave laser, and 1064-nm ns pulsed laser. We provided a comparative study between our system and commercial agent Lipofectamine for transient transfection and stable transfection of HeLa cells with plasmids encoding fluorescent proteins. The quantitative data analysis using flow cytometry, Alamar blue viability assay, and direct fluorescence microscopy revealed higher optoporation efficacy for hard-to-transfect A431 cells and Raw 264.7 cells than lipofection efficacy. Finally, we demonstrated the optoporation performance at the single-cell level by successful delivering PI to the individual CHO cells with revealed high viability for at least 72 h post-irradiation.

JOURNAL OF BIOPHOTONICS 2023; 16:e202200327. [PMID: 36633379 DOI: 10.1002/jbio.202200327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 12/23/2022] [Accepted: 01/10/2023] [Indexed: 05/17/2023]
Abstract
A rapid, precise, and viability-retaining method for cytoplasmic molecule delivery is highly desired for cell engineering. Routine methods suffer from low throughput, lack of selectivity, requirement of helper compounds, predominant endosomal delivery, and/or are restricted to specific molecule classes. Photonic cell manipulation bears the potential to overcome these drawbacks. Here we investigated mammalian cell manipulation by single sub-nanosecond laser pulses. Axial beam waist positioning close to a cell monolayer induced culture vessel damage and zones of cell ablation. Cells at margins of ablation zones exhibited uptake of membrane-impermeant fluorophores and GFP expression plasmids. Increasing Rayleigh-length and beam waist diameter reduced the sensitivity to axial defocusing and resulted in robust molecule transfer. Serial application of single pulses focused over a moving cell monolayer yielded quantitative molecule transfer to cells at rates up to 40%. Our results could be basic to spatially and temporally controlled single laser pulse-mediated marker-free high throughput cell manipulation.
