Myoglobin can also bind CO, and sol-gel with entrapped myoglobin can be used as the sensor for CO by taking advantages of the changes in the absorption spectrum due to protein-CO interaction. [Pg.364]

By controlling the structural and electronic properties of sNPS which are related to the nanocrystallite dimensions and porosity, their surface selectivity and sensitivity to different gases (nitrogen and carbon oxide, vapors of water and organic substances) can be adjusted. This approach for the effective detection of acetone, methanol and water vapor in air was described in [13-15].The minimal detectable acetone concentration was reported to be 12 pg/mL. Silicon sensors for detection of SO2 and some medicines such as penicillin were created [16-18]. sNPS were used for the development of a number of immune biosensors, particularly using the photoluminescence detection. Earlier we developed similar immune biosensors for the control of the myoglobin level in blood and for monitoring of bacterial proteins in air [19-23]. [Pg.89]

Gold nanoparticles have been used to immobilize micro-peroxidase 11,46 tyrosinase,47 and hemoglobin48 to construct amperometric sensors, while silver nanoparticles have been used to enhance electron transfer of cytochrome c and myoglobin onto pyrolitic graphite electrodes.49 The use of semiconductor and oxide nanoparticles has also been reported, such as horseradish peroxidase (HRP) on TiC>2 nanoparticles,50 as well as Fe304 and MnC>4 nanoparticles to immobilize and facilitate direct electron transfer.51... [Pg.285]

A practical approach for toxicity screening combines bioactivation and DNA damage detection into a single biosensor for toxicity screening. To make these types of sensors, ultrathin films (20—4-0 nm thick) containing myoglobin or cytochrome P450cam and DNA were... [Pg.6]

Recently, de novo-synthesized four-helix polypeptides were applied to mimic functions of cytochrome b and to tailor layered cross-linked electrocatalytic electrodes. A four-helix bundle de novo protein (14728 Da) that includes four histidine units in the respective A -helices was assembled on Au electrodes (Figure 22A). Two units of Fe(III)-protoporphyrin IX were reconstituted into the assembly to yield a vectorial electron-transfer cascade [157]. The de novo-synthesized protein assembly forms affinity complexes with the cytochrome-dependent nitrate reductase (NR) and with Co(II) protoporphyrin IX-reconstituted myoglobin [158]. The resulting layered complex of Fe(III) de novo protein-NR or Fe(lll)-de novo protein-Co(II)-reconstituted myoglobin was cross-linked with glutaric dialdehyde to yield electrically contacted electrocatalytic electrodes. The Fe(lll)-de novo protein-NR electrode assembly was applied for the electrocatalyzed reduction NO3 to NOt" and acted as an amperometric sensor (Figure 22B). The Fe(III)-de novo... [Pg.2534]

Myriad metalloproteins bind iron-protoporphyrin IX, known as heme (Fig. 15). Heme protein properties are determined by a variety of factors within the inner coordination sphere and without. These include chemical modifications to the porphyrin macrocycle, different axial ligation, perturbations to conformation, and protein dynamics surrounding the cofactor. Because of the extensive proliferation of heme proteins, we will limit ourselves to a small subset. These will include the cytochromes c, myoglobins, heme oxygenases and peroxidases, and a heme-based chemical sensor. [Pg.137]
