Background:

Accurate detection of pathogenic bacteria is crucial for infection control and food safety.
Traditional methods like culture assays and PCR are effective but slow and require specialized facilities.
There is a growing need for rapid, accessible diagnostic tools for point-of-care applications.

Purpose of the Study:

To review paper-based analytical devices (PADs) for pathogenic bacteria detection.
To highlight PADs with significant point-of-care applicability.
To discuss future challenges and opportunities in this field.

Main Methods:

Literature review of existing studies on PADs for bacterial detection.
Focus on devices suitable for point-of-care use.
Analysis of device characteristics, including speed, cost, portability, and ease of use.

Main Results:

PADs demonstrate potential for rapid, cost-effective bacterial detection.
Several PADs show promise for field deployment in low-resource settings.
Key advantages include portability and minimal training requirements.

Conclusions:

Paper-based analytical devices are a viable alternative to traditional methods for bacterial detection.
PADs offer significant advantages for point-of-care diagnostics, particularly in resource-limited environments.
Further development is needed to address current challenges and optimize PADs for widespread adoption.
