Porous materials with micro/nanostructures have demonstrated intriguing performance in glucose sensor. However, current methods have been limited to complex, time‐consuming, and toxic manufacturing process or unsatisfactory performance, which hugely restricts its practical applications. Herein, for the first time, a fast, simple, and nonpollution femtosecond laser direct writing technology is proposed to fabricate high‐performance glucose sensor. The as‐prepared nickel foam exhibits micro/nanostructures with superhydrophilic property, resulting in superior electrochemical sensing performance toward glucose. The sensitivity is determined to be 13.822 mA cm −2 mM −1 with the detection limit of 1.9 × 10 −6 m , outperforming the results from the most, previously reported works. Meanwhile, the excellent selectivity for glucose detection is also demonstrated in the presence of interferences. This work is an attractive candidate for fast fabrication and designing of high‐performance glucose sensor.
