Strengths and weaknesses of the LFA for phytoproducts analysis

Strengths	Weaknesses
Ready to use	High cost and high labor intensive for antibody production
Rapid device preparation time	Non-specific binding of antibody possibly occurs
Simple analytical procedure	Questioning reproducibility (especially lot-to-lot)
Analyte-specific method	Yes/no results output
Shorter analytical time required compared to conventional chromatographic methods and ELISA	Comparator for semi-quantitative analysis is required
No sample pretreatment step needed	The sensitivity is generally lower than ELISA
Controlled storage condition is not required
Easy to scale-up
Cost-effective method
Easy to convert the signal to value
Applicable in many scenarios
No signal reader needed
No previous sample contamination
Low organic solvent requirement
Low sample volume needed
