Highly specific and sensitive detection is critical in clinical diagnostics and research assays. We specialise in producing high-quality conjugates for lateral flow assays, ELISA, chemiluminescent, and fluorescence-based detection platforms. Our experience in labelling biomolecules with enzymes, fluorophores, and nanoparticles ensures precise signal amplification, leading to more reliable diagnostic results. Whether for infectious disease testing, biomarker screening, or point-of-care diagnostics, our conjugation strategies enhance assay performance and sensitivity.
Nanoparticle Functionalisation
Nanoparticles are increasingly used in biomedical applications, from imaging to targeted drug delivery. Our expertise in nanoparticle conjugation includes gold nanoparticles (AuNPs), magnetic beads, quantum dots, polymeric nanoparticles, and liposomes. We offer surface functionalisation with antibodies, peptides, DNA/RNA, and small molecules, enabling enhanced targeting, improved pharmacokinetics, and reduced immunogenicity in therapeutic and diagnostic applications.

​​
Types of Bioconjugation We Offer
We employ a variety of industry-leading bioconjugation techniques to ensure optimal results for our clients. Each method is selected based on the biomolecule’s stability, functional groups, and intended application.
​
Covalent Conjugation
Covalent linkages provide stable and irreversible attachment between biomolecules, ensuring robustness and reproducibility. This technique is particularly useful in antibody-drug conjugates, protein labelling, and nanoparticle functionalisation, where long-term stability is essential. We offer a variety of chemistries, including amine, thiol, carboxyl, and azide-alkyne reactions, to ensure compatibility with a wide range of biomolecules.
​
Enzyme-Mediated Conjugation
Using enzymes for conjugation allows for high specificity and site-selective attachment without disrupting the biomolecule’s activity. Enzyme-mediated strategies such as sortase, transglutaminase, and oxidoreductase-based conjugation enable gentle modification of proteins and antibodies, maintaining their function while achieving precise control over conjugation sites.
​
Click Chemistry
Click chemistry is a highly efficient and bio-orthogonal conjugation method, offering rapid reaction times, high yield, and minimal by-products. We utilise copper-catalysed azide-alkyne cycloaddition (CuAAC), strain-promoted azide-alkyne cycloaddition (SPAAC), and Diels-Alder reactions, which are widely applied in biomolecule labelling, drug conjugation, and bioimaging applications.
​
Nanoparticle Bioconjugation
Our nanoparticle bioconjugation services involve the surface modification of gold nanoparticles, magnetic beads, polymeric nanoparticles, and liposomes for applications in targeted drug delivery, imaging, and biosensing. We ensure optimal ligand density, orientation, and stability, providing nanoparticles with enhanced functionality and biocompatibility.
​
PEGylation
PEGylation involves the attachment of polyethylene glycol (PEG) chains to proteins, peptides, or small molecules to enhance their solubility, half-life, and stability in biological systems. This technique is commonly used in therapeutic protein engineering and nanoparticle coatings, reducing immunogenicity and increasing circulation time for enhanced therapeutic efficacy.

​
The Science Behind Bioconjugation
​
Bioconjugation is a highly controlled chemical process that allows for the functionalisation of biomolecules through specific chemical linkages. The choice of conjugation strategy depends on multiple factors, including molecular stability, functional group availability, linker length, and intended application. By carefully selecting the appropriate chemistry, we ensure the preservation of biomolecular activity while optimising performance in therapeutics, diagnostics, and nanotechnology applications.
​
Key Chemical Reactions in Bioconjugation
Several well-established bioconjugation chemistries are used to achieve stable and efficient biomolecule functionalisation:
​
-
Amine-reactive conjugation – Commonly uses N-hydroxysuccinimide (NHS) esters and isocyanates to form stable amide bonds with lysine residues in proteins, ensuring robust and reproducible linkage.
​
-
Thiol-reactive conjugation – Employs maleimides, haloacetamides, and disulfide exchange reactions to selectively target cysteine residues, enabling site-specific modification of proteins and peptides.
​
-
DBCO (Dibenzocyclooctyne) Chemistry – A strain-promoted azide-alkyne cycloaddition (SPAAC) reaction that enables copper-free click chemistry. DBCO-azide reactions offer high specificity, bioorthogonality, and rapid reaction kinetics, making them ideal for live-cell labelling, in vivo imaging, and nanoparticle conjugation.
​
-
Carbohydrate-based conjugation – Utilises the oxidation of glycoproteins to create aldehyde-functionalised sugars, which can then react with hydrazine and aminooxy compounds for controlled biomolecule labelling.
​
-
Photoaffinity labelling – Uses photo-reactive crosslinkers to covalently bond molecules upon light activation, allowing for spatially controlled bioconjugation in live-cell studies and molecular interaction analysis.
​
By leveraging these bioconjugation strategies, we achieve precise modifications that retain the structural and functional integrity of biomolecules, ensuring they perform optimally in their intended applications.

Site-Specific Conjugation
Traditional bioconjugation methods often lead to heterogeneous mixtures due to random modifications at multiple functional sites. Site-specific conjugation enables the precise attachment of functional groups at predetermined locations, resulting in uniform products with predictable behaviour. Our expertise includes:
​

​
-
Glycan-based conjugation – Exploiting natural glycosylation sites to create site-specific protein labelling strategies.
​
Multi-Functional Bioconjugation
​For applications requiring complex molecular interactions, multi-functional bioconjugates allow for enhanced targeting, detection, and therapeutic efficacy. Examples include:
​
-
Multi-arm PEG conjugates – Attaching multiple active components to a single polymer scaffold for enhanced drug delivery and increased circulation time.
​
