NanoSight NS300
NanoSight NS300 utilises the particle characterisation technology, Nanoparticle Tracking Analysis (NTA), to visualise and measure particles in suspension (aqueous solution only) in terms of size, light scattering intensity, fluorescence and count. NTA is a video-based analysis for particles between 20-2000 nm* (*material dependent). Its applications includes protein aggregation, exosome and microvesicle research, and drug delivery systems.
MicroCal PEAQ (Isothermal Titration Calorimeter – ITC)
This is the gold standard technique to study label-free biomolecular interactions in-solution and is a thermodynamic technique that directly measures the heat released or absorbed during a biomolecular binding event. It enables the accurate determination of binding constants (KD), reaction stoichiometry (n), enthalpy (ΔH) and entropy (ΔS). This provides a complete thermodynamic profile of the molecular interaction. The sample size for binder (e.g. proteins) is 300 ml and the minimum requirement for the concentration of binder is 1 mM while that for the ligand is 10 mM. Both NanoSight and MicroCal PEAQ ITC are available to all School of Medicine, internal Deakin University researchers, as well as external scientists from other research facilities.
No training of these instruments will be provided. Samples will be run by members of Prof. Wei Duan’s Lab.
To gain access to these instruments, please provide a copy of standard operating procedure (SOP) and complete the application form below. This is to ensure that the experimental condition (eg. buffer used, nanoparticle waste management, etc.) is suitable and would not damage the instruments, and comply with regulatory requirements. Once the SOP is approved, your booking can be made.

NanoSight NS300 (Nanoparticle Tracking Analysis) (KA4.308)
NanoSight NS300 utilize Nanoparticle Tracking Analysis (NTA) to characterize nanoparticles from 10nm - 2000 nm*(*dependent on material) in solution. Each particle is individually but simultaneously analysed by direct observations of diffusion. This particle-by-particle methodology produces high resolution results for particle size distribution and concentration while visual validation gives users extra confidence in the data. As well as particle size and concentration,protein aggregation and viscosity can all be analysed, while a fluorescence mode provides detection of labelled particles.
The NanoSight NS300 system uses a 405 nm (violet) laser source to excite suitable fluorophores whose fluorescence can then be determined using long-pass 430 nm emission filter.
