“…262 Au NPs enhance the conductivity and sensitivity of the electrode and allow for the passive adsorption of doxorubicin-specific monoclonal Abs onto the electrode surface. The sensor detects doxorubicin concentrations in two ranges, that is, 2.5−30 pg mL −1 and 30−1000 pg mL −1 , with a LOD of 1.7 pg mL 264 In the second study, 17 molecules of serratiopeptidase per Fe 3 O 4 NPs (average size 13 nm) with 67% enzymatic activity is determined by mass measurement.…”

“…These materials are used in many devices, orthopedic and dentistry implants [1][2][3] . Among many advantages of AISI 316L one could mention its mechanical properties, the easiness of formability and its relatively low cost, especially when compared to other metallic materials, such as titanium alloys [4][5][6][7][8] .…”

The silicon alkoxides-based coating is an alternative to control the release of cytotoxic ions through metal implants. This study evaluated the influence of the number of layers of a hybrid coating on the surface of austenitic stainless steel AISI 316L on the corrosion resistance. This coating was produced from the precursors of silicon alkoxides 3-(trimethoxysilyl)propyl methacrylate (MAP) and tetraethoxisylane (TEOS) obtained by sol-gel process, and easily applied by dip-coating. Results indicated that a single layer of coating in the substrate showed a better protection than two layers. This single layer developed by the combination of the precursors TEOS-MAP was enough to create a compact and uniform film with good adherence to AISI 316L and higher electrochemical development.A single layer of TEOS-MAP coating is more adequate as a protective coating for the AISI 361L than the sample subjected to two layers and the non-coated substrate, because this film ensures its integrity in an aggressive environment.

“…Another impedimetric biosensor based on Au nanoparticles was introduced by Rezaei et al The stainless steel (SS) working electrode was modified with 3-aminopropyltriethoxysilane (APTES) and then AuNP was deposited onto the APTES modified electrode by electrochemical method. The resulting impedimetric immunosensor was used for the determination of doxorubicin by immobilizing specific monoclonal antibodies on the surface of APTES-gold nanoparticle modified electrode [28].…”

A ltın nanopartiküller (AuNPs) ile zenginleştirilmiş 5-amino-2-mercapto-1,3,4-thidiazole (AMT) modifiye impedimetrik sensörler, Hepatit B virüsüne (HBV) ilişkin dizi seçimli DNA hibridizasyonunun elektrokimyasal olarak izlenmesi için geliştirilmiştir. AMT-AuNP-PGE ler daha fazla miktarda DNA'nın AMT-AuNPs-PGE yüzeyine bağlanması için uygun bir yüzey sağlamış ve daha tekrarlanabilir impedimetrik sinyaller vermiştir. AMT-AuNP ile modifiye edilmiş DNA biyosensörlerin seçimliliği, hedef DNA, veya diğer DNA dizileri; rastgele dizi (NC), mutasyonlu dizi (MM) varlığında test edilmiştir. Tayin sınırı 86 µg/mL olarak hesaplanmıştır. Anahtar KelimelerAltın nanopartiküller, 5-amino-2-mercapto-1,3,4-thidiazole, DNA hibridizasyonu, impedimetrik sensor. A B S T R A C T5 -amino-2-mercapto-1,3,4-thidiazole (AMT) enriched gold nanoparticles (AuNPs) modified impedimetric sensors were developed for the electrochemical monitoring of sequence-selective DNA hybridization related to Hepatitis B virus (HBV). AMT-AuNP-PGEs presented more repeatable impedimetric responses and provided a suitable surface for more DNA binding onto AMT-AuNPs-PGE surface. The selectivity of DNA biosensor modified with AMT-AuNP was investigated in the presence of target DNA, or the other DNA sequences; e.g, noncomplementary (NC), or mismatch (MM) DNA sequences. The detection limit was calculated as 0.86 µg/mL.
