Core Synthesis Facilities: The Molecular Bridge Between Chemistry and Biology
How specialized research centers are transforming scientific discovery by connecting chemical synthesis with biological applications
The Missing Link in Scientific Discovery
"The biggest stumbling block for biological sciences turned out to be synthetic organic chemistry," observed Elias A. Zerhouni, former Director of the National Institutes of Health 1 .
This statement captures a fundamental challenge in modern research: biologists frequently identify promising molecular targets that could revolutionize medicine, but lack the specialized expertise to create the precise chemical tools needed to study them. Similarly, chemists can design remarkable molecules, but may struggle to connect them to relevant biological systems. This critical gap between chemical synthesis and biological application has long hindered scientific progress.
Enter Core Synthesis Facilities—highly specialized research centers that serve as molecular bridges, transforming abstract scientific concepts into tangible chemical reality. These facilities function as scientific powerhouses where chemistry and biology converge, enabling researchers to tackle questions that would otherwise remain inaccessible.

What Exactly Are Core Synthesis Facilities?
Core Synthesis Facilities are centralized laboratories equipped with sophisticated instrumentation and staffed by expert chemists who provide specialized synthetic services to the broader research community 2 . Think of them as molecular kitchens where scientists can bring their recipes for novel compounds and have them prepared by master chefs of chemical synthesis.
Collaborative Environment
These facilities eliminate the need for every research laboratory to maintain expensive equipment and develop specialized synthetic expertise in-house, making cutting-edge research more accessible and cost-effective.
Technology Incubators
Originally established primarily to provide access to specific technologies, they have expanded to become incubators for new technologies and comprehensive service providers 2 .
The Evolution of Core Facilities
| Era | Primary Focus | Services Offered | Relationship with Researchers |
|---|---|---|---|
| 1990s | Specific technologies | Stand-alone services (e.g., DNA sequencing) | Transactional service provider |
| 2000s | Technology access + basic analysis | Data generation + preliminary analysis | Technical support role |
| 2010s-Present | Comprehensive solutions | Experimental design to data interpretation | Strategic research partner |
This evolution reflects a broader trend in scientific research toward interdisciplinary collaboration and resource sharing. As noted in a recent analysis, "Core facilities—originally founded to give scientists access to a specific technology or service—have expanded to become incubators for new technologies and services" 2 .
The Molecular Toolkit: What Happens Inside These Facilities?
Step inside a modern synthesis facility, and you'll encounter a sophisticated array of instruments that seem straight out of science fiction. At the Institute of Biological Chemistry in Taipei, for instance, researchers have access to a CEM Liberty Blue Microwave Peptide Synthesizer that can create peptides (short protein chains) in hours rather than days—including an impressive record of synthesizing an 86-unit peptide 3 .
Advanced instrumentation in a modern synthesis facility enables precise molecular construction and analysis.

A Closer Look: The DNA Oligonucleotide Synthesis Service at CNPEM
To truly appreciate the work of synthesis facilities, let's examine a specific service offered by the Brazilian Center for Research in Energy and Materials (CNPEM). Their Biomolecule Synthesis Facility provides researchers with custom DNA oligonucleotides—short DNA sequences that serve as essential tools for countless biological experiments 4 .
Methodology: From Digital Sequence to Physical DNA
Proposal Submission
CNPEM opens its submission portal to research proposals annually. From June to November 2025, for instance, academic researchers can submit requests for specific DNA sequences through CNPEM's online system 4 .
Technical Evaluation
The facility's experts evaluate each proposal for technical feasibility and alignment with their mission before proceeding with synthesis.
Automated Synthesis
The actual synthesis occurs using automated solid-phase chemical synthesis, a sophisticated technique that builds DNA chains one nucleotide at a time on a solid support 4 .
Purification & Quality Control
Following synthesis, the DNA undergoes rigorous purification using either cartridge-based methods or Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) for higher purity requirements 4 .
Results and Impact: Enabling Diverse Research Programs
The oligonucleotides produced through this service become essential reagents in research laboratories across Brazil and beyond. A single synthesis run can yield multiple sequences tailored to different research needs:
| Sequence Length (base pairs) | Modification Type | Scale (nmol) | Primary Research Applications |
|---|---|---|---|
| 18-22 | None (standard) | 25-100 | PCR primers, standard molecular biology |
| 25-40 | 5'-FAM labeling | 50 | Fluorescence-based detection, imaging studies |
| 60-80 | 3'-Biotin | 50 | Affinity purification, protein binding studies |
| 30-50 | Internal phosphorothioate | 25 | Nuclease resistance, therapeutic development |
Democratizing Research Tools
These custom DNA tools enable research that might otherwise be impossible for individual laboratories lacking synthetic expertise or equipment. The service exemplifies how core facilities democratize access to sophisticated research tools, allowing scientists to focus on their biological questions rather than technical challenges.

Challenges and Future Directions
Despite their proven value, core synthesis facilities face significant challenges that must be addressed to ensure their continued success and impact.
Sustainability Challenges
Creating a sustainable operational model remains difficult, as fee-for-service arrangements alone typically cannot cover equipment costs, depreciation, and personnel salaries 6 . Facilities must therefore balance cost recovery with their educational and research missions, often requiring institutional support to remain viable.
Innovation vs. Service
Another challenge lies in maintaining the delicate balance between service and innovation. As one analysis notes, "innovation is an assignment that cannot be done as part of the routine business, but requires its own time and resources" 2 . Facilities must therefore carefully manage their workflows to accommodate both routine service work and the development of new methodologies.
Quality Management Solutions
Many facilities are addressing these challenges through implementation of Quality Management Systems (QMS) that streamline operations and enhance reproducibility 7 . These systems incorporate process mapping, standardized procedures, and continuous improvement metrics that increase efficiency and customer satisfaction while maintaining scientific rigor.
Process Mapping
Standardization
Continuous Improvement
Future Directions
Looking ahead, synthesis facilities will likely continue to expand their service portfolios while developing new collaborative models. The trend toward "whole-package" services that guide researchers from experimental design through data interpretation will probably continue, with facilities playing increasingly integral roles as research partners rather than service providers 2 .
The ongoing integration of artificial intelligence and machine learning into synthesis planning and optimization represents another promising direction for these facilities, potentially further accelerating the pace of molecular discovery.
The Unsung Heroes of Modern Science
Core Synthesis Facilities represent one of the most important—if underrecognized—elements of the modern scientific ecosystem. By bridging the historical gap between chemistry and biology, these facilities enable research that would otherwise be impossible, accelerate the pace of discovery, and train the next generation of scientists in interdisciplinary thinking.
They transform abstract concepts into tangible tools, moving science from "what if" to "what is." As research grows increasingly interdisciplinary, the role of these facilities will only expand. They stand as testaments to the power of collaboration, specialization, and shared resources in advancing human knowledge.
In the ongoing quest to understand and improve the biological world, Core Synthesis Facilities provide the essential molecular bridges that connect chemical ingenuity to biological discovery.
