“…Reports have been published on the development of point‐of‐care testing strips using biosensors for the detection of microorganisms in clinical and biological samples (Fani, Rezayi, et al, 2019; Khorasani, Langari, Sany, Rezayi, & Sahebkar, 2019; Rezayi, Ghayour‐Mobarhan, et al, 2018; Rezayi, Ghasemi, Karazhian, Sookhakian, & Alias, 2014; Said et al, 2016; Said, Rezayi, Narimani, Manan, & Alias, 2015; Sany et al, 2016).

“…In electrochemical biosensors, a solid electrode acts as the basic electrode to transmit the signal throughout the detection process, converting the produced signal into electrical signals, including current, potential, impedance, and coulometry signals (Abraham et al, 2015; Ahmadzadeh, Rezayi, Faghih‐Mirzaei, Yoosefian, & Kassim, 2015; Ahmadzadeh, Rezayi, Kassim, & Aghasi, 2015; Rezayi, Karazhian, et al, 2014; Rezayi, Gholami, Said, & Alias, 2016; Said et al, 2015). Due to the various biological targets of M. tb detection, the reported electrochemical biosensors for M. tb diagnosis have been divided into two categories of electrochemical DNA and immune biosensors (Fani et al, 2018; Mahmoodi et al, 2019; Rasouli et al, 2018; Rezayi, Farjami, Hosseini, Ebrahimi, & Abouzari‐Lotf, 2018).…”

Tuberculosis (TB) is referred to as a "consumption" or phthisis, which has been a fatal human disease for thousands of years. Mycobacterium tuberculosis (M. tb) might have been responsible for the death of more humans than any other bacterial pathogens. Therefore, the rapid diagnosis of this bacterial infection plays a pivotal role in the timely and appropriate treatment of the patients, as well as the prevention of disease spread. More than 98% of TB cases are reported in developing countries, and due to the lack of well-equipped and specialized diagnostic laboratories, development of effective diagnostic methods based on biosensors is essential for this bacterium. In this review, original articles published in English were retrieved from multiple databases, such as PubMed, Scopus, Google Scholar, Science Direct, and Cochrane Library during January 2010-October 2019. In addition, the reference lists of the articles were also searched. Among 109 electronically searched citations, 42 articles met the inclusion criteria. The highest potential and wide usage of biosensors for the diagnosis of M. tb and its drug resistance belonged to DNA electrochemical biosensors (isoniazid and rifampin strains). Use of biosensors is expanding for the detection of resistant strains of anti-TB antibiotics with high sensitivity and accuracy, while the speed of these sensory methods is considered essential as well. Furthermore, the lowest limit of detection (0.9 fg/ml) from an electrochemical DNA biosensor was based on graphene-modified iron-oxide chitosan hybrid deposited on fluorine tin oxide for the MPT64 antigen target. According to the results, the most common methods used for M. tb detection include acid-fast staining, cultivation, and polymerase chain reaction (PCR). Although molecular techniques (e.g., PCR and real-time PCR) are rapid and sensitive, they require sophisticated laboratory and apparatuses, as well as skilled personnel and expertise in the commentary of the results. Biosensors are fast, valid, and cost-efficient diagnostic method, and the improvement of their quality is of paramount importance in resource-constrained settings.

Human papillomavirus type (HPV) is a common cause of sexually transmitted disease (STD) in humans. HPV types 16 and 18 as the highest risk types are related with gynecologic malignancy and cervical cancer (CC) among women worldwide. Recently, considerable development of genosensors, which allows dynamic monitoring of hybridization events for HPV‐16 and 18, has been a topic of focus by many researchers. In this systematic review, we highlight the route of development of DNA‐based genosensory detection methods for diagnosis of high risk of HPV precancer. Biosensor detection methods of HPV‐16 and 18 was investigated from 1994 to 2018 using several databases including PubMed, Cochrane Library, Scopus, Google Scholar, SID, and Scientific Information Database. Manual search of references of retrieved articles were also performed. A total of 50 studies were reviewed. By analyzing the most recent developed electrochemical biosensors for the identification of HPV, we observed that the sensor platform fabricated by Wang et al. holds the lowest detection limit reported in the literature for the DNA of HPV‐16. Up to this date, optical, electrochemical, and piezoelectric systems are the main transducers used in the development of biosensors. Among the most sensitive techniques available to study the biorecognition activity of the sensors, we highlight the biosensors based fluorescent, EIS, and QCM. The current systematic review focuses on the sensory diagnostic methods that are being used to detect HPV‐16 and 18 worldwide. Special emphasis is given on the sensory techniques that can diagnosis the individuals with CC. © 2018 BioFactors, 45(2):101–117, 2019

“…In this work, GO is synthesized based on the modified Hummers method and employed to generate mode-locked pulses using home-made D-shaped fiber at 1.55 µm so as to form solitons in the cavity [32][33][34]. The group velocity dispersion (GVD) effect as well as self-phase modulation (SPM) defines the shape of the optical soliton, and balancing the influence of GVD and SPM allows its profile to remain unaltered during propagation.…”

Novel D-shaped fiber fabrication method for saturable absorber application in the generation of ultra-short pulses

et al. 2017

View full text Add to dashboard Cite

A cost-efficient, time-saving and effective technique for the fabrication of D-shaped fibers is presented, to provide a platform with a strong evanescent field to be used as a saturable absorber (SA). This technique provides flexibility by removing the required portion of the fiber, and a small polished length which offers a unique opportunity to deposit SA on its surface by simply submerging it in the SA solution without high losses. A compact fiber laser utilizing a graphene oxide coating on a fabricated D-shaped fiber as an SA capable of generating ultrashort pulses is designed and verified. We report the generation of ultrafast pulses as short as 227 fs with a 34.7 MHz repetition rate, having a 3 dB bandwidth of 14 nm at the 1570 nm center wavelength.
