Corresponding average number of pixels obtained from the optical imaging system for each entity

Single entity	Average number of pixels	Normalized amplification rate*
Escherichia coli	1,911	1
Anti-E. coli bead	7,335	3.8
Uncoated magnetic bead	81,510	42.6

Note:

^*Normalized amplification rate is based on average number of pixels for an entity.
