New human health challenges arise in response to an array of geopolitical and socioeconomical factors including radical global population growth, paradigm shifts in social behaviour, or increased urbanization and loss of land for agriculture. This creates unique opportunities for innovators and original manufacturers (OEMs) who are willing to collaborate and deliver solutions to the next generation of environmental and human health problems.
Biosensor Chips: Resolving Next-Gen Human Health Challenges
Biosensor chips are at the heart of technological initiatives in a wide range of market segments, including those geared towards tackling the critical challenges of the day. Recent reports estimate the value of the global photoplethysmography (PPG) biosensor market will top USD $839 million by 2028 due to rising cardiovascular disorders and the surge of smart wearable adoption around the world.
Much of this success has been driven by tandem advances in micromanufacturing and photonics. OEMs can now deliver precisely micro-structured platforms with absolute accuracy and high repeatability, providing valuable substrates for biosensor manufacturers to rapidly develop prototypes and proofs of concept, thus accelerating the often-laborious research and development (R&D) workflow.
A recent example of the successful integration of micro-structured silicon chips with bespoke optics includes a brand-new biosensor for cancer diagnostics. Silicon-based nanostructures with features on the order of 100 nanometres (nm) efficiently trap light on the sample—chip interface, dramatically increasing the biosensor’s sensitivity to the presence of biomarkers.
Biosensor chips based on non-optical sensing platforms are also subject to enormous growth and improvement. Researchers in chemistry and bioengineering at the University of Maryland demonstrated the effectiveness of gold-coated silicon wafers with a biobased (catechol—chitosan) redox capacitor in detecting redox-active bacterial metabolites. It was used to research a novel amplification system for the detection of redox-active virulence factors with the aim of pioneering earlier detection solutions for life-threatening infections of Pseudomonas aeruginosa.
Platypus Technologies was the OEM provider of 100 nm silicon chips coated with high-purity gold for the University of Maryland’s biobased redox capacitor. With greater demand than ever for high-sensitivity, rapid, miniature diagnostic devices, we anticipate further interest from research communities and manufacturers of novel biosensor chips.
