Abstract
Enzyme mimicking nanomaterials, nanozymes, have gained considerable interest in the scientific community because of their superior properties compared to natural enzymes, including their high stability at extreme conditions, cheaper availability, and ease of synthesis. Herein, we report novel colloidal gold nanoparticles - graphene nanoplatelets - chitosan (CS) with peroxidase mimicking properties used to carry out highly sensitive and selective immunoassay for porcine gelatin detection. The interaction between anti-gelatin antibody conjugated nanozyme with porcine gelatin proteins produced an ultrasensitive immunoassay response in the form of a colourimetric signal directly proportional to the porcine gelatin protein concentration. The nanozyme produced a colourimetric response in the presence of its substrate, 3,3',5,5'-tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2), demonstrating its peroxidase mimicking properties. The results revealed that the nanozyme exhibited remarkable selectivity and sensitivity in the assay, detecting proteins at concentrations as low as 86.42 pg/mL. Additionally, the immunosensor demonstrated a broad linear detection range spanning from 200 pg/mL to 2 ng/mL.

Food Chem 2024; 437:137827. [PMID: 37897827 DOI: 10.1016/j.foodchem.2023.137827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 10/14/2023] [Accepted: 10/19/2023] [Indexed: 10/30/2023]
Abstract
Electrochemical aptasensors have emerged as promising platforms for effectivelydetection of various target analytes. Here, we developed a sensitive and selective electrochemical aptasensor for zearalenone (ZEN) determination based on a bimetallic organic framework (CuBi-BPDC). The results of HR-TEM, FE-SEM, XPS, etc. indicate the CuBi-BPDC possessing mixed nodes of Cu(II) and Bi(III) and multilayered nanosheets bearing nanoparticles. Due to its improved electrochemical activity and strong affinity for aptamers, the CuBi-BPDC-based aptasensor obtains a low limit of detection of 0.19 fg mL-1 (IUPAC S/N = 3) in a wide range of 1 fg mL-1-10 ng mL-1 via EIS and 0.73 fg mL-1 from 0 fg mL-1 to 1 × 107 fg mL-1 via DPV for ZEN detection, respectively. Moreover, the excellent selectivity allows this aptasensor to specifically identify ZEN from other interfering substances in raw milk and rice, indicating the potential applicability of the CuBi-BPDC-based aptasensor in sensitive and selective detection of ZEN.

CA19-9 and CEA biosensors in pancreatic cancer. Clin Chim Acta 2024; 554:117788.

Abstract
Cancer is a complex pathophysiological condition causing millions of deaths each year. Early diagnosis is essential especially for pancreatic cancer. Existing diagnostic tools rely on circulating biomarkers such as Carbohydrate Antigen 19-9 (CA19-9) and Carcinoembryonic Antigen (CEA). Unfortunately, these markers are nonspecific and may be increased in a variety of disorders. Accordingly, diagnosis of pancreatic cancer generally involves more invasive approaches such as biopsy as well as imaging studies. Recent advances in biosensor technology have allowed the development of precise diagnostic tools having enhanced analytical sensitivity and specificity. Herein we examine these advances in the detection of cancer in general and in pancreatic cancer specifically. Furthermore, we highlight novel technologies in the measurement of CA19-9 and CEA and explore their future application in the early detection of pancreatic cancer.

PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 302:123142. [PMID: 37454434 DOI: 10.1016/j.saa.2023.123142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 07/10/2023] [Accepted: 07/11/2023] [Indexed: 07/18/2023]
Abstract
Accurate and sensitive detection of carcinoembryonic antigen (CEA) is essential for the detection of various diseases in healthcare and the medical field. Currently, due to the high false negative rate of CEA assay in clinical setting and its use as a common indicator for early cancer screening, a novel CEA detection method with high sensitivity, increased specificity and the lower cost has become a clinical challenge. Here, a facile sandwich type immunosensor based on surface-enhanced Raman scattering (SERS) was presented including 4-mercaptobenzonitrile (4MBN) labeled gold core-silver shell nanoparticles (Au@4MBN@Ag NPs) as SERS tag and 4-mercaptophenylboronic acid (4-MPBA) functionalized two-dimensional (2D) silver nanoparticle film (Ag FM) as SERS capture substrate for CEA detection. A linearity of 10-9-10-14M was observed with high sensitivity and excellent selectivity for the detection of CEA. Additionally, the spiking experiment yielded 105.33-127.00% recovery with variation coefficients below 10% demonstrating high assay accuracy and precision. The immunosensor we proposed here is a promising approach to quantify CEA in liquid biopsy samples with high sensitivity, which could be further developed for early cancer screening.
