Claim:
1. A method of transporting one or more drops, cells, or compositions and forming a droplet-based concentration gradient of the one or more drops, cells, or compositions in a first solution through a microfluidic device, wherein the method comprises: providing a sample solution comprising the one or more drops, cells, or compositions to an inlet of an microfluidic device, wherein the microfluidic device comprises the inlet in fluid communication with one or more conduits, one or more parking loops ( filling at least one of the fluidic traps ( forming the droplet-based concentration gradient of the one or more drops, cells, or compositions in the first solution by moving the first solution through the one or more conduits such that the first solution merges with the stationary sample solution filled within the at least one of the fluidic traps ( thereby reducing a concentration of the sample solution within the at least one of the fluidic traps (
