Apparatus, system and method for dispensing a particle-laden fluid from a fluid holding and dispensing micro-feature and/or multiple lysing channel structures. In some implementations, the apparatus includes: a chamber having one or more surfaces that define a volume to receive fluid containing particulate matter, a soluble surface coating on a portion of the one or more surfaces of the chamber, and an outlet port to dispense at least a portion of the fluid from the chamber. In some implementations, the particle-laden fluid may be whole blood, and the soluble surface coating may include reagents and/or dyes that are diffused into the whole blood received within the chamber to generate signals to visualize various cellular components. In some implementations, the apparatus may also include a second soluble surface coating on portions of surfaces of the multiple lysing channel structures.
