Fast bacterial identification in urine samples was achieved by capturing bacteria on a microchannel silicon nanowire microfluidic chip, followed by MALDI-TOF MS detection. Under the optimized conditions, bacteria with a concentration of 10⁶ CFU mL⁻¹ in urine samples could be identified without culture. If cultured for 4 hours, bacteria with a concentration as low as 10³ CFU mL⁻¹ were identified.

使用微通道硅纳米线微流控芯片结合MALDI-TOF MS捕获和检测尿液细菌

通过在微通道硅纳米线微流控芯片上捕获细菌，然后进行MALDI-TOF MS检测，可以快速识别尿液样品中的细菌。在最佳条件下，无需培养即可鉴定尿液样品中浓度为10 ⁶ CFU mL ^-1的细菌。如果培养4小时，则鉴定出浓度低至10 ³ CFU mL ^-1的细菌。
