By exploiting the plasmonic properties of nanomaterials, surface-enhanced Raman offers a dramatic increase in sensitivity compared to conventional Raman spectroscopy, enabling the detection of analytes down to parts-per-billion (ppb) levels. We’ve used our state-of-the-art nanoparticle deposition technology to develop high-performance, low-cost substrates for surface-enhanced Raman, enabling laboratories of all sizes to achieve cheap, versatile and […]

Surface-enhanced Raman spectroscopy (SERS) is used to detect and characterise samples. Although it was first discovered in the late 1970s for laboratory use, it has been utilised outside of labs since the advent of nanostructured substrates in the 1990s In this blog post, we will explain what SERS technology is used for alongside its benefits.

Nanotechnology is a rapidly developing scientific discipline with an ever-growing range of critical sub-fields. Thin-film engineering, microelectromechanical systems (MEMS), state-of-the-art therapeutics, and so much more, are built on research and development (R&D) at the nanoscale. Novel materials are central to so many of these breakthroughs; specifically nanoparticles. Colloidal nanoparticles serve an array of functions, and

Spherical gold nanoparticles are advanced nanomaterials having diverse applications such as targeted drug delivery, radiotherapy, biological imaging, sensors, and chemical catalysis. Gold nanoparticles can be produced by either chemical methods such as aerosol-assisted chemical vapour deposition, hydro-thermal reduction, and microemulsion or by physical procedures such as plasma-assisted vacuum deposition, laser ablation, spray pyrolysis, and ion

Gold nanospheres are advanced nanomaterials with a strong potential in high-tech biomedical applications. It is possible to modify gold nanospheres’ optoelectronic and physiochemical properties by altering their structure, size, and width-to-height ratio.
