“…In the MCFIA approach, the peristaltic pump is the most used device for solutions propelling Pires et al 2007; Garcia and Reis 2006;Maruchi and Rocha 2006;Vieira et al 2006;Rodenas-Torralba et al 2005). Recently, the solenoid micro-pump has been introduced as an alternative to peristaltic pump (Lapa et al 2002;Rocha et al 2005;Santos and Masini 2007;Ribeiro et al 2007;Santos and Masini 2007;Carneiro et al 2005), presenting, as advantages, small size and commuting features, and thus permitting its use to replace both peristaltic pump and solenoid valve.…”

This review highlights some relevant contributions proposed by Brazilian analytical research groups mainly after 2004. This year was chosen due to an earlier publication of an overview with similar scope by Andrade et al. (2004). The selected papers are representative, but the authors have not tried to present a comprehensive overview of the aforementioned period. The chosen areas for discussion were automation in analytical chemistry, chemometrics, chromatography, capillary electrophoresis and mass spectrometry, electroanalytical chemistry, environmental analytical chemistry, preconcentration and separation procedures, and spectrochemical analysis. A glimpse of the Brazilian contributions shows the stage of development of analytical chemistry in Brazil, with emphasis on major advancements and critical needs.

“…However, electrochemical biosensors are widely used in clinical practice for the sensitive detection of glucose. The majority of these conventional glucose sensors are based on enzymatic methods adapting different approaches such as electrochemical, colorimetric, and chemiluminescence [5][6][7]. They initially utilize glucose oxidase (GOD) enzyme, based on a co-product of enzymatic oxidation of glucose molecules by tracking H 2 O 2 to detect and measure glucose.…”

A novel, low-cost, sensitive microwave microfluidic glucose detecting biosensor incorporating molecularly imprinted polymer (MIP) is presented. The sensing device is based on a stub resonator to characterize water glucose solutions. The tip of one of the stubs is coated with MIP to increase the selectivity of the sensor and hence the sensitivity compared to the uncoated or to the coated with non-imprinted polymer (NIP) sensor. The sensor was fabricated on a FR4 substrate for low-cost purposes. In the presence of the MIP, the sensor loaded with a glucose solution ranging from 50 mg/dL to 400 mg/dL is observed to experience an absorption frequency shift of 73 MHz when the solutions flow in a microfluidic channel passing sensing area, while the lower limit of detection (LLD) of the sensor is discovered to be 2.4 ng/dL. The experimental results show a high sensitivity of 1.3 MHz/(mg/dL) in terms of absorption frequency.

“…Entretanto, a aplicabilidade desses métodos pode ser limitada pela cinética reacional, sensibilidade, robustez ou por se tratar de métodos não automatizados. Sendo assim, os métodos automatizados conduzidos em sistemas de análises em fluxo devem ser enfatizados (OLIVEIRA e FATIBELLO, 1999;ULASOVA et al, 2003;CARNEIRO et al, 2005).…”
