Abstract Microbial attachment is a problem of vital importance and economic significance, particularly in marine environments. Slippery Liquid Infused Surfaces (SLIPS) have attracted considerable interest as solution to this challenge. In the present study, we hypothesized that Saint John's Wort Oil (SJWO) could provide an eco-friendly alternative synthetic oils, combating microbial with non-toxic chemicals. We developed hydrophobic electrospun porous cellulose acetate fiber layer, coated silica nanoparticles (SiO 2 NPs), infused SJWO. The optimization process involved measuring sliding velocity, number SiO NP layers, amount lubricant, infusion time. optimal configuration demonstrated velocity 0.31 cm/s on 10° slope. Antibacterial tests revealed SLIPS reduced bacterial Pseudomonas aeruginosa from 1.67 ± 0.03 × 10 6 CFU/mL glass substrates 2.85 0.07 5 for SLIPS. Similarly, anti-algae performance against Chlorella sp. showed significant reduction optical density 0.92 0.01 0.19 SLIPS, chlorophyll content was 7.24 µg/mL 3.70 0.77 µg/mL. findings indicate SJWO-infused robust effective method reducing attachment.
