A stable naked-eye colorimetric sensor for monitoring release of extracellular gamma-aminobutyric acid (GABA) neurotransmitter from SH-SY5Y cells

Lipoic Acid Functionalized Silver Nanoprisms for Colorimetric Sensing of γ‐Aminobutyric Acid, Selenite and Myoglobin

“…Table 1 displays a comparison of LA-AgNPRs-based colorimetric method with the reported methods for sensing of GABA, selenite, and myoglobin. [35][36][37][39][40][41][43][44][45][61][62][63][64][65][66][67][68] It can be noticed that LA-AgNPRs acted as promising colorimetric sensor for simultaneous detection of three analytes and the LODs of the method either comparable or superior to the reported methods, signifying the potentiality of the method for three analytes assay.…”

Recent Developments in Isoindole Chemistry

“…Many isoindoles are fluorescent and have found recent and widespread use in analytical methods for the detection of amino acids [42][43][44][45] and other amine-containing compounds. 46 In such methods, the amino acids or amines are derivatized as fluorescent isoindoles 23 via a condensation reaction between their amino groups 22 and ortho-phthalaldehyde (OPA, 21) (Scheme 3).…”

Microwave‐assisted synthesis of blue fluorescent molybdenum nanoclusters with maltose‐cysteine Schiff base for detection of myoglobin and γ‐aminobutyric acid in biofluids

“…The Myo-MIP PHEMATrp nanoparticles were then coated on the SPR sensor's gold surface and were used for the detection of myoglobin in aqueous solutions as well as in serum samples. [10] Assessment of the GABA level in biofluids is crucial for clinical and biochemical research, and detection techniques like electrochemistry, [11] high-performance liquid chromatography, [12,13] Raman spectroscopy, [14] fiber-optic sensor, [15] and colorimetry [16] have been reported for the detection of GABA. However, the lengthy timeframes, complex sample pretreatments, and high cost of these approaches render them ineffective for the efficient measurement.…”
