Including LNPs, traditional liposomes, and SLNs, they deliver small-molecule drugs and nucleic acids in vivo. Needing additives like suspending agents, they require characterization to clarify post-formulation co-existing structure, avoid carrier damage, and ensure drug encapsulation/release.
Covering polymer nanospheres (e.g., PLGA) and micelles (e.g., PEGylated), they enable targeted delivery with good biocompatibility. Prone to mixing with other colloids, they need the service to test structural compatibility, preventing abnormal size or reduced drug loading.
Including silica, gold nanoparticles, and quantum dots, they combine with organic colloids (e.g., LNPs) for multi-functional delivery. With big density/charge differences, they risk uneven dispersion, requiring the service to test co-dispersibility and stability for system uniformity.
Including surfactant-coated O/W emulsions, microemulsions, and nanosuspensions, their stability relies on surfactant layers. Adding other colloids may cause surfactant competition and system damage, needing the service to evaluate co-existing stability.
Covering lipoproteins (e.g., LDL), VLPs, and exosomes, they serve as delivery carriers with natural targeting. When combined with exogenous colloids, they need the service to analyze biocompatibility and structure, avoiding damage and ensuring in vivo safety.

| Small-Angle X-Ray Scattering (SAXS) | Analyzes X-ray scattering to infer 3D configuration; non-destructive, resolves sub-nanoscale internal structure. |
| Field-Flow Fractionation-Multi-Angle Light Scattering (FFF-MALS) | Separates LNPs by size, uses MALS to measure size and encapsulation efficiency, and suits complex LNPs. |
| Liquid Chromatography-Evaporative Light Scattering Detector (LC-ELSD) | Separates lipids via LC, quantifies with ELSD to calculate drug loading; high lipid quantification accuracy. |
| Differential Scanning Calorimetry (DSC) | Monitors heat flow changes to assess thermal stability; small sample, simulates storage/in vivo temperatures. |

DLS provides only the external size and homogeneity. Our service looks inside the particle. You could have the perfect size (low PDI) but an unstable internal structure (e.g., a supercooled melt or an unwanted lipid polymorph) that will cause catastrophic drug expulsion days or weeks later. We provide the data to guarantee the internal stability.
Our specialized techniques are optimized for virtually any complex colloidal carrier, including Lipid Nanoparticles (LNP), Solid Lipid Nanoparticles (SLN), Nanostructured Lipid Carriers (NLC), Lipoplexes, Polyplexes, and various hybrid vectors like cationic nanoemulsions.
We define quantitative structural QC metrics for your optimal formulation (e.g., a specific WAXS peak intensity or a DSC melting profile). Manufacturing success is then defined by matching these established structural fingerprints, ensuring true batch consistency at large volumes, thereby reducing risk and rework.
Absolutely. Our procedures follow rigorous protocols, and the high-resolution, quantitative nature of SAXS/WAXS and DSC data is exactly what regulatory agencies require to demonstrate control over the critical quality attributes (CQAs) related to your drug product's physical stability and performance.
Creative Biolabs is the definitive partner for securing the physical integrity and performance of your advanced nanomedicines. Our Custom Co-existence of Addition Colloidal Structure Characterization Service delivers critical, high-resolution data on internal particle architecture, resolving stability challenges before they impact your clinical timeline or regulatory submissions. We translate complex scientific analysis into a concrete formulation strategy.
