Abstract

Malaria and bacterial infections remain a life-threatening disease with a significant global impact. This study aimed to develop nanogels (NGs) of lavender (Lavandula angustifolia Mill.) and geranium (Pelargonium graveolens L’Hér.) essential oils (EOs) with promising repellent and antibacterial effects. The NGs were formulated using a nanoemulsion-based gel approach; nanoemulsion droplet sizes and zeta potentials were obtained as 146 ± 7 and 106 ± 6 nm and −23.2 ± 0.7 and −17.4 ± 1 mV, respectively. The ATR-FTIR analysis confirmed the successful loading of EOs in NGs. Repellent bioassays conducted on Anopheles stephensi Liston. mosquitoes demonstrated that geranium NG (140 min) was as effective as DEET (140 min), a widely used repellent. Antibacterial tests showed that the nanogels effectively reduced bacterial growth, with the geranium NG exhibiting over 90% reduction against Escherichia coli Migula. The lavender NG displayed higher efficacy against Staphylococcus aureus Rosenbach. These findings highlighted the potential of nanogels containing EOs as promising repellents and antibacterial agents, offering a sustainable and eco-friendly approach for vector control and bacterial infections.

薰衣草和天竺葵精油载体纳米凝胶具有良好的驱蚊和抗菌效果
疟疾和细菌感染仍然是一种威胁生命的疾病,对全球具有重大影响。本研究旨在开发具有良好驱蚊和抗菌效果的薰衣草(Lavandula angustifolia Mill.)和天竺葵(Pelargonium graveolens L'Hér.)精油(EOs)纳米凝胶(NGs)。采用基于纳米乳液的凝胶方法配制了 NGs;纳米乳液液滴尺寸和 Zeta 电位分别为 146 ± 7 和 106 ± 6 nm,以及 -23.2 ± 0.7 和 -17.4 ± 1 mV。ATR-FTIR 分析证实了在 NGs 中成功添加了环氧乙烷。对列斯顿按蚊进行的驱蚊生物测定表明,天竺葵 NG(140 分钟)与广泛使用的驱蚊剂 DEET(140 分钟)同样有效。抗菌测试表明,纳米凝胶能有效减少细菌生长,其中天竺葵 NG 对大肠杆菌 Migula 的抑制率超过 90%。薰衣草 NG 对金黄色葡萄球菌 Rosenbach 具有更高的功效。这些发现凸显了含有环氧乙烷的纳米凝胶作为驱虫剂和抗菌剂的潜力,为病媒控制和细菌感染提供了一种可持续的环保方法。
