TABLE 1.
Comparison of the various supramolecular architectures used for fluorescence-based pesticide detection and the notable advantages/disadvantages of each method.
| Supramolecular scaffold | Range of LODs | Significant advantages | Notable drawbacks |
|---|---|---|---|
| Polymers | 1.3E-6 µM137–100 µM126 | Conjugated fluorescent polymers have extremely high sensitivity; MIPs have high selectivity | Synthetic procedures can be cumbersome; organometallic polymers can be toxic and/or have toxic degradation products |
| Macrocycles | 1E-6 µM211–1,040 µM297 | Ability to rationally design components of the macrocycle to achieve target application | Synthetic procedures are nearly always cumbersome; can have poorly defined cavity for analyte binding |
| Nanomaterials | 1.14E-7 µM367–12.2 µM350 | High sensitivity, selectivity, and stability in a broad range of environments | Toxicity of the metal components can be of concern; as can the degradation and disposal of such materials |
| Metal-organic frameworks | 5.2E-6 µM413–2.6 µM420 | Easy and highly modular synthesis; large cavities able to bind multiple pesticide analytes | Limited stability in aqueous media; limited options for post-synthetic modifications |
