Table 3. List of Fluids; labeling: AAAAmmdd where ¨mm¨ is the month and ¨dd¨ is the day of creation.

Fluid label	Part Number	Origin	Description	Refr. Index
Bact1202A	XL1 blue with contamination	CBS	E.coli bacteria grown for 5 hrs and transferred to Urine1202. Note that the culture was contaminated before incubation with an unknown bacteria measured to have a lower concentration then E.coli and probably a gram positive species.	1.32276
BSA0917	A0281-250 mg	S-A	Albumin from bovine serum (100 μg/ml). 2 mg of bovine serum albumin was dissolved in 2 ml of PBS and stored in one vial of 2 ml (1 mg/ml) at 4° C. On the day of use, 100 μl from the BSA vial is diluted in 900 μl of PBSG0917 resulting in a 100 μg/ml solution for use in the experiments.	N/A
BSA1202	A0281-250 mg	S-A	Albumin from Bovine Serum (100 μg/ml). This batch mixed from 100 μl of PBS with 900 μl of PBSG1124. Same protocol as BSA0917.	N/A
DIH2O	D11931	Barnstead	Ultra pure water, 18.2 MΩ-cm, < 1CFU/ml, < 1μM/ml (theoretical RI = 1.3206)	1.31977
ECOLI0917	XL1 blue	CBS	E.coli bacteria grown for 4.3 hrs then transferred to PBSG0917.	1.32854
ECOLI0924	XL1 blue	CBS	E.coli bacteria grown for 4.3 hrs then transferred to Urine0924.	N/A
ECOLI1117	XL1 blue	CBS	E.coli bacteria grown for 6 hrs, then transferred to Urine1120 and concentration measured with plate culture.	N/A
ECOLI1126	XL1 blue	CBS	E.coli bacteria grown for 7 hrs then transferred to Urine1126.	N/A
GNeg	AB41202	ABCAM	50 μg/ml of gram negative antibody in solution of PBSG0715. 100 μl of gram negative antibody was diluted in 3900 μl of PBSG0715 and stored in 10 vials of 0.4 ml (50 μg/ml) at 4° C.	N/A
GPos	AB20344	ABCAM	50 μg/ml of gram positive antibody in solution of PBSG0917. 0.5 ml of gram positive antibodies was diluted in 0.5 ml of PBS and stored in 2 vial of 0.5 ml (50 μg/ml) at 4° C.	N/A
GProt0715	P4689-1MG	S-A	1 mg of protein G (immunoglobulin-binding protein expressed in group C and G Streptococcal bacteria) was dissolved in 4 ml of PBSG0715 solution and stored in 4 vials of 1 ml (0.25 mg/ml) by freezing at −20° C. On the day of use, a protein G vial was thawed and 200 μL diluted in 800 μL of filtered PBSG solution resulting in a 50 μg/ml solution used to functionalize the bare gold surface of a waveguide with a monolayer of protein G.	N/A
HKECOL1001	XL1 blue	CBS	E.coli bacteria grown for 7 hrs in LB broth, transferred to PBS solution, then heat killed in oven at 80° C for 60 min.	N/A
HKECOL1008	XL1 blue	CBS	HKECOL1001 bacteria transferred to Urine1008 by spinning at 3000 RPM for 7 min.	N/A
LB Broth	L3022	S-A	Mix one pouch in 500 ml of DIH2O.	N/A
PBS	P-5368	S-A	Mix one pouch in 1L DIH2O ml (theoretical RI = 1.3329).	1.32351
PBSG0715	49767-250 ml	S-A	66.66 g of glycerol in 500 ml of PBS.	1.33425
PBSG0917	49767-250 ml	S-A	33.33 g of glycerol in 500 ml of PBS.	1.32854
PBSG1124	49767-250 ml	S-A	PBSG0917 sterilized in a microwave oven for 20 min. Final concentration: approximately 10 g/100 ml.	1.33152
SDS	71725-50G	S-A	5 g of sodium dodecyl sulfate in 1L of DIH2O.	N/A
