Our Service Portfolio

Creative Biolabs provides a comprehensive microfluidic polymer nanoparticle synthesis service package that covers the major technical steps required for successful nanoparticle development.

Formulation Design and Feasibility Assessment

Our scientists work closely with clients to evaluate the intended application, target payload type, desired particle size range, release profile, route of administration, stability requirements, and analytical endpoints. Based on these inputs, we recommend a suitable synthesis strategy and help define the critical formulation and process variables.

Our feasibility assessment may include:

Evaluation of polymer and solvent compatibility
Selection of appropriate nanoparticle preparation routes
Preliminary assessment of payload incorporation strategy
Identification of key process constraints
Proposal of a practical microfluidic workflow for development

This stage is particularly important for projects involving novel polymers, sensitive biomacromolecules, low-solubility compounds, or highly specific particle performance criteria.

Microfluidic Route Selection

Polymer nanoparticles can be prepared through several microfluidic strategies depending on the formulation system and final product requirements. We help select the most appropriate route based on your chemistry and performance goals. Common approaches include:

Nanoprecipitation-based microfluidic synthesis
Solvent displacement and controlled self-assembly
Droplet-assisted particle generation
Emulsification–solvent evaporation workflows
Core-shell or multi-phase particle construction
Hybrid polymer-lipid assembly

Our team considers how each route influences particle size, encapsulation efficiency, throughput, reproducibility, and downstream scalability.

Chip and Mixer Selection

Creative Biolabs supports the selection and customization of chip configurations suitable for polymer nanoparticle synthesis, including designs optimized for laminar mixing, hydrodynamic flow focusing, multi-inlet feeding, and enhanced chaotic mixing.

Depending on project requirements, we may employ or develop systems based on:

Y-shaped or T-shaped microfluidic inlets
Flow-focusing designs
Staggered herringbone mixers
Split-and-recombine geometries
Zigzag or serpentine channels
Parallelized mixer arrays for throughput enhancement

Chip materials and fabrication routes are selected according to chemical resistance, biocompatibility, pressure tolerance, optical transparency, and intended application environment.

Process Optimization

Microfluidic nanoparticle synthesis is highly parameter-dependent. Our service includes systematic optimization of critical conditions to achieve target particle attributes. We can study the effects of individual variables or perform multi-parameter optimization campaigns, depending on project scope.

Typical optimization parameters include polymer concentration, solvent and antisolvent composition, aqueous-to-organic phase ratio, total flow rate, flow rate ratio, surfactant type and concentration, temperature, pH or ionic strength, payload concentration, and post-formation stabilization conditions.

Payload Encapsulation Development

A major advantage of polymer nanoparticles is their capacity to encapsulate or associate with a wide range of active ingredients. Creative Biolabs supports encapsulation development for different cargo classes, including:

Hydrophobic small molecules
Hydrophilic therapeutic agents
Peptides and proteins
Nucleic acids and oligonucleotides
Dyes and contrast agents
Combination payloads

We tailor encapsulation strategies according to the physicochemical properties of the payload and the intended release mechanism. Particular attention is paid to preserving payload integrity during processing and improving loading performance where possible.

Particle Characterization

Accurate nanoparticle characterization is essential for formulation evaluation and decision-making. Our characterization support can include assessment of particle size, size distribution and polydispersity, morphology, zeta potential, encapsulation efficiency, drug loading, colloidal stability, release behavior, storage compatibility, and response to biological or environmental conditions.

By integrating synthesis and characterization into one development workflow, we help clients move more efficiently from concept to validated formulation candidates.

Customization Capabilities

One of the major strengths of our service is customization. We recognize that polymer nanoparticle development is rarely a one-size-fits-all task. Different applications demand distinct particle attributes, synthesis routes, and performance priorities.

Customization Capabilities	Descriptions
Polymer Selection Support	We work with a broad range of polymer systems and help match polymer chemistry to functional needs such as biodegradability, hydrophobicity, charge behavior, ligand attachment, responsiveness, and mechanical stability.
Surface Engineering	Surface properties strongly influence nanoparticle stability, biodistribution, cell interaction, and targeting potential. We support strategies for tuning surface charge, stealth behavior, colloidal stabilization, and functionalization readiness.
Responsive and Functional Nanoparticles	For advanced applications, we can help develop polymer nanoparticles designed to respond to environmental triggers such as pH, redox conditions, temperature, ionic strength, or enzymatic activity.
Multi-Component Systems	Many next-generation formulations require more than one structural or functional component. Our microfluidic platforms can support the controlled assembly of multi-component nanoparticles, including polymer blends, polymer-lipid hybrids, and co-loaded systems.
Application-Oriented Development	We can tailor synthesis workflows for specific research or product development contexts, including intravenous delivery studies, mucosal delivery concepts, gene delivery exploration, imaging applications, or material-focused performance requirements.

Optimization of PLGA nanoparticle formulation via microfluidic and batch nanoprecipitation techniques

In this study, the researchers combined experimental nanoprecipitation and computational fluid dynamics (CFD) modeling to optimize PLGA nanoparticle formulation using both traditional batch and microfluidic methods. While Design of Experiments (DoE) was used to optimize the batch process, microfluidic mixing was systematically explored by varying flow parameters such as the flow rate ratio (FRR) and total flow rate (TFR). They compared two microfluidic mixer designs with Y-junction and three-inlet junction geometries to evaluate their impact on the mixing efficiency and nanoparticle formation.

A: Our microfluidic polymer nanoparticle synthesis services can support encapsulation or association of multiple payload categories, including hydrophobic small molecules, hydrophilic compounds, peptides, proteins, nucleic acids, imaging agents, fluorescent probes, and certain combination payloads. The appropriate encapsulation strategy depends on the physicochemical properties of the active ingredient and the target performance of the final formulation.

Q: Can you help if I only have an early-stage concept and not a finalized formulation?

A: Yes. Many clients come to us during the early stages of development. Even if you do not yet have a finalized polymer selection, solvent system, or nanoparticle preparation route, our team can help evaluate feasibility, recommend technical directions, and design an initial microfluidic screening plan. We support both exploratory projects and more advanced formulation development programs.

Q: What particle size range can typically be achieved?

A: The achievable particle size depends on the polymer chemistry, formulation composition, microfluidic chip design, and processing parameters. In many cases, microfluidic systems can generate nanoparticles with tunable sizes in the nanometer range and with relatively narrow size distributions. If your application requires a specific size window, we can incorporate that objective into the process development strategy.

Q: Can you support the preparation of surface-functionalized polymer nanoparticles?

A: Yes. We can support projects involving surface-tailored or functionalizable polymer nanoparticles. Depending on the formulation design, this may include nanoparticles intended for ligand conjugation, charge tuning, stealth behavior, improved colloidal stability, or other surface-related performance features. Surface engineering strategies can be incorporated into the project during formulation design or post-synthesis development.

Q: Do you offer custom microfluidic chip design for nanoparticle synthesis?

A: Yes. If a project cannot be adequately addressed by standard chip configurations, we can discuss custom microfluidic chip or mixer designs. Device selection depends on formulation chemistry, throughput targets, channel compatibility, mixing requirements, and downstream integration needs. Our experience in microfluidic design allows us to align device architecture with practical nanoparticle synthesis goals.
