Analysis of itemized cost for synthesizing 5 mg Ag NP@N-GQD, which requires 0.8 mg N-GQD and 10 mg AgNO3.
| Component | Chemical Agent | ACS number | Pack size | Price (USD) | Chemical Quantity for synthesizing 5 mg Ag NP@N-GQD | Cost (USD) | Cost distribution |
|---|---|---|---|---|---|---|---|
| Ag NP | AgNO3 | 7761–88–8 | 5 g | 24.9 | 10.0 mg | 4.98 × 10−2 | 99.67% |
| N-GQD | Citric acid | 77-92-9 | 500 g | 90.3 | 0.8 mg | 1.45 × 10−4 | 0.29% |
| Dicyandiamid | 461-58-5 | 1000 g | 45.7 | 0.4 mg | 1.83 × 10−5 | 0.04% |
The measured baseline glucose level (diluted by 10 times) is 0.21 mM. The first and second values in the column of “Estimated increase in glucose concentration” give the mean value and the standard deviation, respectively. Note that the Mean Percent Error is calculated as (ΔEstimated − ΔExpected)/ΔExpected × 100%, where ΔEstimated represents the mean estimated increase in glucose concentration and ΔExpected represents the expected increase in glucose concentration.
