Super-resolution microscopy is widely used in the development of novel antimicrobial testing . In the presented work, a scanning protocol was developed by the method of scanning ion-conducting microscopy (SICM), which makes it possible to study microorganisms without rigid fixation and in saline, obtaining an index map of nanosized structures. The effect of azole and echinocandins drugs on the morphology and mechanical properties of Candida parapsilosis yeast was studied. The findings are consistent with previously proposed drug mechanisms and reports that have examined antifungal agents using AFM, SEM, and TEM. We have shown that the SICM method is capable of scanning and detecting the nanomechanical properties of yeast non-invasively.
超分辨率显微镜在新型抗菌测试的开发中被广泛应用。在本研究中,通过扫描离子传导显微镜(SICM)方法开发了一种扫描协议,该协议使得在无需刚性固定且在盐溶液中的情况下研究微生物成为可能,从而获得纳米级结构的索引图。研究了唑类和棘白菌素类药物对近平滑念珠菌酵母形态和力学性能的影响。这些发现与先前提出的药物作用机制以及使用原子力显微镜(AFM)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)研究抗真菌剂的报告一致。我们已经表明,SICM方法能够非侵入性地扫描和检测酵母的纳米力学性能。
