Surface chemistry for challenging LFA and SPR applications
Innovative surface chemistry for gold nanoparticles used in Lateral Flow Assays
Lateral Flow Assays (LFAs) have proved their utility to lead massive diagnostic campaigns, the Covid-19 pandemic giving us a striking example.
Yet for some applications, LFAs remain not reliable enough and fail to deliver a definitive diagnosis. This limitation partly comes from a lack of control of the nanoparticle functionalization, which can lead to poor sensitivity and cause non-specific interactions with the membrane.
Kimialys offers off-the-shelf and custom surface chemistries to LFA developers willing to improve the limit of detection and stability of their gold nanoparticle-based assay. Kimialys is also open to transfer its technology onto new materials (magnetite, latex, cellulose, etc.) at request.
Innovative surface chemistry for gold biochips used in Surface Plasmon Resonance
Gold biochips are routinely used by pharmaceutical companies all along their drug discovery process, from drug candidate screening to biomolecular interaction analysis (kinetics, affinity, avidity, etc.), using a Surface Plasmon Resonance (SPR) instrument.
Yet, current biochips show damaging limitations in performance, mostly in specificity when it comes to complex media (cell extract, serum, etc.).
Kimialys tackes this issue by providing SPR users with off-the-shelf and custom ready-to-use gold biochips, enabling sensitive, robust and reproducible SPR measurements while keeping background noise level at minimum. Our technology works with all types of ligands and SPR instruments, without changing the habits of the user.
