Optimization of paper-based substrates for surface enhanced raman spectroscopic biosensor development
Get PDFAdvancements in the field of analytical chemistry have greatly expanded the development of biosensors for the detection of a wide array of diseases. This study aims to optimize an affordable paper-based nanocomposite biosensor that utilizes surface-enhanced Raman spectroscopy (SERS). Specifically, it investigates the preparation parameters for a paper-based SERS substrate, including nanoparticle administration and drying procedures. A particular focus of this work is to assess how the wax-defined paper channels can effectively enhance SERS intensity. The results revealed that while the wax-printed wells can define the nanoparticle administration for SERS detection, wax backing may reduce the sensitivity of SERS by preventing two-directional solution drying, promoting a non-uniform distribution of nanoparticles on paper substrates. The limit of detection in terms of the number of nanoparticles within the paper-based SERS platform was determined, showing a limit of detection of 0.02% of a theoretical monolayer of gold nanoparticles. These findings, along with preliminary on-going work, suggest that this platform can be expanded with the use of click chemistry for the development of highly sensitive paper-based microfluidic SERS biosensors for the detection of biomarkers in various diseases, such as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)
Torus links (4,2) Olivewood. Figure 2
No full textA 4,2 torus link carved from Olivewood. completed four new wooden torus knot sculptures, two from Purpleheart wood and two from Olivewood. One of the Purpleheart pieces came from a 2 x6 x6 block, and all the others were from 2 x4 x4 blocks. I made two (3,5) torus knots, one from the larger Purpleheart block and one from an Olivewood block. The other two smaller blocks were made into torus links, that is, two (2,1) torus knots linked, which happens when you make a (4,2) torus ``knot .https://orb.binghamton.edu/mathematical_sculptures/1620/thumbnail.jp
