Let’s face it, organic chemistry can seem difficult to learn, Formula: https://www.ambeed.com/products/333-93-7.html, Especially from a beginner’s point of view. Like 333-93-7, Name is 1,4-Diaminobutane dihydrochloride, molecular formula is amides-buliding-blocks, belongs to amides-buliding-blocks compound. In a document, author is Faig-Marti, Jordi, introducing its new discovery.
Three-dimensional (3D) metal-semiconductor nanostructures as surface-enhanced Raman scattering (SERS) substrates were designed by in situ electrodeposition of gold nanoparticles (AuNPs) or in situ photodeposition of silver nanoparticles (AgNPs) on gallium nitride (GaN) nanoflowers (NFs) supports fabricated by metal-assisted photochemical etching of single crystalline GaN. 3D AuNPs/GaN NFs and AgNPs/GaN NFs substrates exhibit excellent enhancement effect for Rhodamine 6G (R6G) due to more hot spots in the same probing volume compared to 2D GaN based substrates. The enhancement factors of the AuNPs/GaN NFs and AgNPs/GaN NFs substrates are up to 2.1 x 10(7) and 5.9 x 10(7), respectively, and the corresponding detection limits of R6G are 10(-8) and 10(-10) M, respectively. Moreover, further study reveals both substrates have good reproducibility and long-term stability. The performance of the prepared substrates for biological application was demonstrated by the detection of bovine serum albumin (BSA). A series of characteristic bands of amides suggest BSA can be well adsorbed on the surface of the AuNPs/GaN NFs and AgNPs/GaN NFs substrates, which demonstrates our substrates have good biocompatibility and are promising candidates for SERS biosensors.
