Electrohydrodynamic jetting (EHDJ) which is also known as electrosprays (ES) has recently been elucidated as a unique electrified biotechnique for the safe handling and deployment of living organisms. This high intensity electric field driven jetting methodology is now referred to as "bioelectrosprays" (BES). Previously these charged jets have only been shown to jet-process immortalized cells which have undergone expected cellular behavior when compared with control cells. In this paper we demonstrate the ability to jet process primary living organisms in the stable conejetting mode. Finally the viability of the bio-electrosprayed living organisms has been assessed employing a flow cytometry approach which forms the discussion in this paper. Our findings further establish BES as a competing biotechnique, which could be employed for the deposition of primary living organisms according to a predetermined active cellular architecture. One day this could be used for the fabrication of viable tissues and organs for repair or replacement. These advanced studies carried out on BES have direct widespread applications ranging from developmental biology to regenerative and therapeutic medicine, which are a few amongst several other areas of study within the life sciences.
电流体动力喷射(EHDJ),也被称为电喷雾(ES),最近已被阐明为一种用于安全处理和部署活生物体的独特带电生物技术。这种由高强度电场驱动的喷射方法现在被称为“生物电喷雾”(BES)。以前,这些带电射流仅被证明可对永生化细胞进行喷射处理,与对照细胞相比,这些永生化细胞具有预期的细胞行为。在本文中,我们展示了以稳定的锥射流模式对原生活生物体进行喷射处理的能力。最后,采用流式细胞术方法评估了生物电喷雾处理后的活生物体的活力,这构成了本文的讨论内容。我们的研究结果进一步确立了生物电喷雾作为一种有竞争力的生物技术的地位,该技术可根据预定的活性细胞结构用于原生活生物体的沉积。有朝一日,这可用于制造用于修复或替换的有活力的组织和器官。对生物电喷雾进行的这些前沿研究具有广泛的直接应用,从发育生物学到再生医学和治疗医学,这些只是生命科学中众多其他研究领域中的几个。
