Foodborne and waterborne infections are major causes of worry around the world.
Escherichia coli (E. coli) pathogenic strains like O157:H7 are a leading cause of food and
water-borne illness epidemics all over the world. E. coli is a pathogen present in the lower
intestinal of warm-blooded species, it is used to detect fecal contaminants in specimens
collected. Human infections can be caused by even low levels of E. coli O157:H7 (10–100
viable organisms). The standard techniques for food assessment are mainly conducted in
centralized laboratories and involve long analysis times and complex instrumentation.
Sensors based on screen-printed electrodes (SPEs) had grown in popularity in this context
due to their favorable properties, such as ease of use and portability, which allow for
quick analysis in point-of-need circumstances. The application of SPE-based sensors in
the management of food contamination as beneficial analytical techniques to traditional
techniques offers for quick inspection at any step in the food manufacturing process, reducing
food waste and preventing foodborne infections. However, a screen-printed electrode (SPE)
may not be as durable as a traditional electrode, such as a glassy carbon or gold disc,
and the surface of its working electrode is not as perfect as that of a mirror-like polished
solid electrode, the advantages of SPEs in terms of cost and size have led to an increase
in their use as (bio) sensing transducers in recent years. The field of research for detection
of E.coli using sensors is very extensive and actively studied by researchers in this area of
interest. Here, publication for E.coli and nanoparticle sensor growth research were analyzed
from Scopus databases. The keywords were biosensor, E.coli, screen printed electrode and
nanoparticle reported from 2012 to 2021. This bibliometric analysis concluded that E.coli
biosensors development involved multidisciplinary collaborations of biology, analytical
chemistry, optoelectronics, material science, engineering and data science and each subject
area plays an important role in establishing biosensors for E. coli detection.
