Nanozymes are an excellent class of optical reporters for the development of sensitive biosensors for widespread applications. In this study, platinum-palladium (Pt-Pd) nanoparticles were applied as signal amplifier in a dual-lateral flow immunoassays (LFIA) and integrated with a smartphone-based device for use in simultaneous detection of Salmonella Enteritidis and E. coli O157:H7. After optimization, the LODs were calculated to be ∼20 CFU/mL for Salmonella Enteritidis and ∼34 CFU/mL for E. coli O157:H7, respectively. The greatly improved sensitivity was contributed by the peroxidase-like catalytic activity of the Pt-Pd nanoparticles for signal enhancement and the parallel design of dual-detection for noninterference. The estimated recoveries of the dual-LFIA range from 91.44% to 117.00%, which indicated the developed method is capable of detecting live bacteria in food samples. This approach provides an attractive platform for Salmonella Enteritidis and E. coli O157:H7 detection using a smartphone-based device as the sole piece of equipment, indicating great promise for foodborne pathogen analysis or in-field food safety tracking.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 August 2025.
All research outputs
#11,109,863
of 33,779,198 outputs
Outputs from ACS Applied Materials & Interfaces
#8,080
of 30,208 outputs
Outputs of similar age
#135,637
of 374,739 outputs
Outputs of similar age from ACS Applied Materials & Interfaces
#182
of 638 outputs
Altmetric has tracked 33,779,198 research outputs across all sources so far. This one has received more attention than most of these and is in the 66th percentile.
So far Altmetric has tracked 30,208 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one has gotten more attention than average, scoring higher than 70% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 374,739 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 62% of its contemporaries.
We're also able to compare this research output to 638 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 69% of its contemporaries.
