The LFIAs for the rapid discovery of FBs are reported by using lots of probes not only gold. The efficiency of the LFIA developed by the authors in term of level of sensitivity, uniqueness and precision are not comparable with those of records. In the United States in 2016, 64,000 overdose deaths were reported to be related to the abuse of opioids, consisting of prescription medicines (e.g. oxycodone), narcotics (e.g. heroin), or artificial opioids (e.g. fentanyl). The current spike in the visibility of artificial opioids in lots of heroin dispersed on the street existing certain and substantial difficulties to law enforcement. Synthetic opioids are very hazardous substances, which can conveniently be inhaled. This kind of direct exposure can cause accidental overdoses by law enforcement and also various other first -responders answering calls entailing immoral medications consisting of these materials. Due to this severe toxicity, it is necessary for these individuals to have devices that can be conveniently deployed for precise presumptive field tests.
