A Diagnostic Chip for the Colorimetric Detection of Legionella pneumophila in Less than 3 h at the Point of Need. BIOSENSORS 2024; 14:228. [PMID: 38785702 PMCID: PMC11118137 DOI: 10.3390/bios14050228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 04/23/2024] [Accepted: 05/01/2024] [Indexed: 05/25/2024]
Abstract
Legionella pneumophila has been pinpointed by the World Health Organization as the highest health burden of all waterborne pathogens in the European Union and is responsible for many disease outbreaks around the globe. Today, standard analysis methods (based on bacteria culturing onto agar plates) need several days (~12) in specialized analytical laboratories to yield results, not allowing for timely actions to prevent outbreaks. Over the last decades, great efforts have been made to develop more efficient waterborne pathogen diagnostics and faster analysis methods, requiring further advancement of microfluidics and sensors for simple, rapid, accurate, inexpensive, real-time, and on-site methods. Herein, a lab-on-a-chip device integrating sample preparation by accommodating bacteria capture, lysis, and DNA isothermal amplification with fast (less than 3 h) and highly sensitive, colorimetric end-point detection of L. pneumophila in water samples is presented, for use at the point of need. The method is based on the selective capture of viable bacteria on on-chip-immobilized and -lyophilized antibodies, lysis, the loop-mediated amplification (LAMP) of DNA, and end-point detection by a color change, observable by the naked eye and semiquantified by computational image analysis. Competitive advantages are demonstrated, such as low reagent consumption, portability and disposability, color change, storage at RT, and compliance with current legislation.

Abstract
An urgent need exists for a rapid, cost-effective, facile, and reliable nucleic acid assay for mass screening to control and prevent the spread of emerging pandemic diseases. This urgent need is not fully met by current diagnostic tools. In this review, we summarize the current state-of-the-art research in novel nucleic acid amplification and detection that could be applied to point-of-care (POC) diagnosis and mass screening of diseases. The critical technological breakthroughs will be discussed for their advantages and disadvantages. Finally, we will discuss the future challenges of developing nucleic acid-based POC diagnosis.
