Recover What Matters™—from Surfaces, Swabs, Wipes & Solid-Associated Samples
Important targets don't always begin in liquid.
SurfacePrep™ brings together workflows used to collect or release targets from surfaces, collection devices and selected solid-associated matrices—and move them into a target-bearing fluid that can be conditioned, clarified, concentrated and prepared for downstream analysis.
SurfacePrep™ gets the target from where it starts into the target-bearing fluid. FluidPrep™ takes it from there.
From Surface to Recovered Target
Title
Follow the Target-Bearing Fraction
A SurfacePrep workflow should be designed around where the target is—not simply what the original sample was called.
A microorganism may begin attached to a stainless-steel surface, move onto a polyester wipe during collection, and then be released into an extraction fluid. Once released, the target is no longer simply a "surface sample." It is now present in a target-bearing fluid that can be evaluated for conditioning, clarification and concentration.
This transition connects SurfacePrep directly to FluidPrep™ and the InnovaPrep® 4C Workflow Framework™.
SurfacePrep extends beyond conventional environmental swabbing. The defining characteristic is the transition from a surface-, collection-device- or solid-associated target into a recoverable liquid fraction.
Swabs, wipes, sponges and other collection methods can recover targets from cleanrooms, manufacturing equipment, food-contact surfaces, built environments, aerospace hardware and other surfaces.
Swabs, Wipes & Sponges
A collection device becomes an intermediate carrier of the target. The workflow must then move the collected target efficiently from that carrier into a fluid that can be processed.
Objects, components, foods and other materials may generate target-bearing liquids through washing, rinsing or extraction. Once the target enters the liquid fraction, the workflow can be evaluated using FluidPrep principles.
Solid-Associated Samples
Soils, sediments, powders and other solids may enter a SurfacePrep workflow when the relevant target can be released, washed or suspended into a liquid fraction. Workflow design should consider where the target resides and what must be preserved.
Large-Area Surface Sampling
Title
Low-biomass surface monitoring presents a fundamental sampling challenge: the target may be scarce and distributed across a large area, while downstream analytical methods work with much smaller sample volumes.
Large-area wipe sampling provides a way to collect from substantially more surface area. The recovered wipe extract can then be concentrated to deliver more of the collected target into a manageable volume for downstream analysis.
Explore InnovaPrep's existing Large-Area Surface Sampling Application Note for an established example of the SurfacePrep → FluidPrep workflow.
SurfacePrep uses the same InnovaPrep® 4C Workflow Framework™ used to develop matrix-aware FluidPrep workflows. The framework stays consistent while the specific workflow is adapted to the surface, collection method, recovered matrix, target and intended downstream use.
Consider the original surface or material, sampling area, target class, collection approach, required recovery characteristics and downstream method before selecting the workflow.
Condition
Release the target and make the recovered sample processable.
Conditioning may begin with the release step itself—such as eluting a swab or wipe, washing a surface, dispersing material or selecting an appropriate recovery fluid. Additional conditioning may be considered when sample behavior limits processing.
Clarify
Remove what interferes without removing what matters.
Surface-derived samples may contain fibers, sediment, debris, aggregates or suspended solids. Clarification should improve processability while preserving the analytically relevant target-bearing fraction.
Concentrate
Recover the target from the resulting liquid fraction.
Once the target is present in an appropriate fluid, FluidPrep™ concentration can reduce sample volume and recover retained target material into a small-volume eluate for the intended downstream workflow.

Sample Conditioning
Determine whether the recovered sample requires conditioning to improve target availability or processability before concentration.
Select Concentration Tips, matrix prefilters, upstream clarification products and related consumables based on the recovered sample, target and workflow objective.
SurfacePrep is grounded in real-world workflows for recovering scarce biological targets from demanding environments. NASA-associated work provides particularly strong examples of large-area surface collection, cleanroom bioburden characterization and low-biomass microbial recovery.

SurfacePrep addresses the path from the original surface or material into a target-bearing fluid. Once that transition occurs, FluidPrep™ technologies can be used to manage and concentrate the liquid sample.
CP Select™ uses single-use Concentration Tips to retain selected target fractions from liquid samples. Captured material can then be rapidly recovered into a small-volume eluate using Wet Foam Elution™.
Surface-associated recovery challenges occur across research, manufacturing, environmental monitoring and critical controlled environments. SurfacePrep provides a common workflow framework while allowing collection and processing to be tailored to the application.
