Sunbather:GMP 級 LNP 生產解決方案
將「Lipid Nanoparticles」(LNPs) 與其他奈米藥物推進至「Good Manufacturing Practice」(GMP) 階段,往往伴隨著高昂的成本與繁瑣的製程重新驗證。設備更換、流路變更與混合器差異,都可能導致批次品質不一致,延誤藥物上市時程。
Sunbather 是 Unchained Labs 專為臨床製造設計的 GMP 級 LNP 生產系統。有別於傳統製程放大方案,Sunbather 採用與 Sunscreen 及 Sunshine 完全相同的泵浦技術與 Sunny 微流道晶片,確保研發階段鎖定的製程參數可直接轉用,無需額外優化或重新驗證。
從配方篩選到臨床生產,Sunny Suite 以一致的微流道混合技術貫穿整個開發流程,大幅降低製程轉移的失敗風險,節省時間與成本。

四大臨床級優勢
製程轉移零落差
Sunbather 使用與 Sunshine 相同的高精度連續式注射泵與 Sunny 微流道晶片。在開發階段確立的「Total Flow Rate」(TFR) 與「Flow Rate Ratio」(FRR) 等關鍵參數,可直接套用至 GMP 生產,無需重新優化製程。
GMP 法規合規設計
軟體完全符合「FDA 21 CFR Part 11」規範,具備完整的「Audit Trail」審計追蹤功能與分級權限管理(Administrator / Operator)。系統提供「IQ/OQ」驗證服務,並以品質管理系統(QMS)作為製程管控基礎。
污染防護與流路彈性
配備可完全更換的液體接觸流路(Replaceable Flowpath),包含泵浦閥、注射器與管路,並隨附「Extractables」數據供法規審查。支援單次使用(Single-use)或原位清洗(Clean-in-place, CIP)兩種模式。

About Sunbather - GMP-Ready LNP Production System
Sunbather from Unchained Labs is the GMP-ready solution for lipid nanoparticle (LNP) clinical manufacturing. Designed to eliminate the costly and time-consuming process revalidation typically associated with scale-up to GMP production, Sunbather maintains exact process consistency with its Sunny Suite family members - Sunscreen for high-throughput formulation screening and Sunshine for process optimization.
The system features the same high-precision continuous syringe pump technology and Sunnies microfluidic mixing chips used throughout the Sunny Suite platform. This design philosophy ensures that process parameters developed during the R&D phase, including total flow rate (TFR) and flow rate ratio (FRR), can be directly transferred to GMP manufacturing without additional optimization or validation studies.
Sunbather delivers FDA 21 CFR Part 11 compliant software with comprehensive audit trail functionality and tiered access control (Administrator and Operator levels). The touchscreen kiosk interface is designed for cleanroom environments, enabling fast setup and intuitive operation with minimal training requirements.
Key features include a fully replaceable wetted flow path with accompanying extractables data, supporting both single-use and clean-in-place (CIP) protocols. The system offers throughput up to 1.8 liters per hour, with the capability for parallel operation when higher production volumes are required.
GMP-ready Sunnies are available in multiple geometries including Sunny Trident (reverse-angle mixing with in-line dilution), Sunny X (cross-type mixing), and Sunny T (T-mixing), each offered in various channel sizes to accommodate different flow rate requirements and applications. All chips are manufactured from chemically inert glass with ultra-smooth channel surfaces (±5 nm roughness) to prevent material buildup during extended production runs.
Sunbather is available with installation qualification and operational qualification (IQ/OQ) services, comprehensive user training, and full warranty and maintenance packages. The system is backed by Unchained Labs' Quality Management System (QMS), providing complete material traceability and documentation for regulatory compliance.
Applications include GMP production of mRNA vaccines, mRNA therapeutics, gene therapy vectors, siRNA delivery systems, and other lipid nanoparticle-based drug products. Typical performance specifications include particle sizes of 40-200 nm, PDI below 0.2, and encapsulation efficiency exceeding 90% (formulation dependent).
The Sunny Suite platform represents a complete end-to-end solution for nanoparticle drug development, from initial formulation screening through process optimization to clinical manufacturing. By maintaining identical fluid delivery and microfluidic mixing technology across all three instruments, Sunny Suite enables seamless transitions between development stages, reducing batch failures, saving time and costs, and accelerating the path to market for life-changing vaccines and therapeutics.
