How does DLS technology measure the binding affinity of glyconanoparticles to biomolecules?

DLS technology infers the size and distribution of particles by measuring the fluctuations in the intensity of scattered light in a solution. When glyconanoparticles bind to biomolecules (such as lectins), the hydrodynamic volume of the particles increases, resulting in changes in the intensity of scattered light. By analyzing these changes, we calculate the binding affinity, which is the strength of the interaction between the glyconanoparticles and the biomolecule.

What types of glyconanoparticles and biomolecules can your service be applied to?

Our service has a wide range of applicability and can be applied to many types of glyconanoparticles, including but not limited to nanomaterials such as silica, gold, and silver. At the same time, we are also able to analyze a variety of biomolecules, such as lectins, antibodies, receptors, etc. Our team of experts will tailor the most suitable experimental plan for you according to your specific needs.

This service is further subdivided into Glyconanoparticle Molecule Interaction Analysis Service, which focuses on analyzing the interaction between glyconanoparticles and various biomolecules, providing accurate data support for scientific researchers and product developers.

Harness the Power of DSL for Glyconanoparticle Binding Affinity Analysis

Our DLS-based glyconanoparticle binding affinity analysis leverages the principles of DLS to evaluate the interaction strengths between glyconanoparticles and target lectin proteins. The central tenet of this analysis lies in measuring the changes in the hydrodynamic diameter of glyconanoparticles upon binding with lectins. As interaction occurs, the nanoparticles often form aggregates, leading to observable changes in size that can be quantified using DLS.

Preparation of Glyconanoparticles

Select and prepare nanoparticles such as silica or gold.
Conjugate nanoparticles with desired sugars.

Interaction

Mix prepared glyconanoparticles with targeted lectins under controlled conditions.
Allow the interaction to proceed for the specified time to reach equilibrium.

DLS Measurement

Utilize a DLS instrument to measure the resulting hydrodynamic diameter of both free and lectin-bound glyconanoparticles.
A series of concentrations is reported to derive the detection limit and measure binding constants.

Data Analysis

Analyze DLS data to quantify interaction strength and determine kinetic parameters, including association and dissociation rates.

Our services offer customization to fit specific client needs, including different nanoparticle types and surface modifications to target a wide array of lectins and proteins.

Workflow

First, we receive the glyconanoparticles and lectin samples provided by the client, pre-treat, and label them. Then, we use a DLS nanoparticle sizer to measure the particle size and record the changes in particle size under different lectin concentrations. Next, we use data analysis software to calculate the detection limit and binding affinity. Finally, we provide clients with a detailed customized report containing all key data and result analysis.

Technology: Utilizing solid-phase polymer synthesis to develop a series of precise glycomacromolecules

Published: 2017

Journal: Polymers

IF: 4.7

Results: The article explores the use of glyco-functionalized gold nanoparticles as advanced biosensors and inhibitors due to their strong binding affinity with carbohydrate-specific receptors such as lectins. By utilizing solid-phase polymer synthesis, a series of precise glycomacromolecules were developed, allowing easy chemical modification and functionalization of gold nanoparticles. The study uses UV-Vis spectroscopy, dynamic light scattering, and surface plasmon resonance to analyze the interactions and aggregation behavior of these tailored glyco-gold nanoparticles in the presence of model lectin Concanavalin A.
