“…Particles of n‐BG were used in this study to prepare the composites. These n‐BG particles were fabricated by the flame spraying method as described in Misra et al Appropriate amounts of n‐BG particles were added to a polymer solution (1 g of P(3HB) dissolved in 8 mL of chloroform) to yield composites with 10 wt% n‐BG in the P(3HB) matrix. This mixture was further sonicated for 1–2 min (Ultrasonic Homogenizer US200, Phillip Harris Scientific, UK) to improve the dispersion of the n‐BG particles by segregating possible agglomerations.…”

“…In the work reported here, for potential application in wound healing, nanoscale bioactive glass particles (n‐BG) were incorporated within a biodegradable P(3HB) polymer matrix. The chemical composition of the n‐BG used is not very different from that of the commercially available 45S5 Bioglass ® microscale bioactive glass particles (m‐BG); however, the n‐BG used are spherical in shape with a uniform surface morphology as compared to the m‐BG, which are irregular in size with large agglomerates . The spherical morphology of the ceramic particles with a high specific surface area is crucial for interface effects such as hydroxyapatite (HA) formation and contact activated coagulation .…”

“…It has been observed that the presence of n‐BG particles affects the microstructural, mechanical and biological properties of composite films used for bone tissue engineering applications . However, previous research using P(3HB) as a matrix has considered only films and scaffolds . Microspheres made of P(3HB) are highly interesting as carriers of drug and bioactive particles.…”

Bioactive glass (BG) is considered an ideal material for haemostasis as it releases Ca 2+ ions upon hydration, which is required to support thrombosis. In this study the effect of the presence of the BG nanoparticles in P(3HB) microsphere films on the structural properties, thermal properties and biocompatibility of the films were studied. The nanoscaled bioactive glass with a high surface area was also tested for its in vitro haemostatic efficacy and was found to be able to successfully reduce the clot detection time. In an effort to study the effect of the roughness induced by the formation of HA on the cellular functions such as cell adhesion, cell mobility and cell differentiation, the composite films were immersed in SBF for a period of 1, 3 and 7 days. From the SEM images the surface of the P(3HB)/n-BG composite microsphere films appeared fairly uniform and smooth on day 1, however on day 3 and day 7 a rough and uneven surface was observed. The presence of HA on the composite microsphere films on day 3 and day 7 influenced the surface roughness of the films. However, when the P(3HB)/n-BG 2 composite microspheres with enhanced surface roughness were tested for biocompatibility, reduced amount of protein adsorption and cell adhesion were observed. This study thus revealed that there is an optimal surface roughness for the P(3HB) microsphere films for increased cell adhesion, beyond which it could be deleterious for cell adhesion and differentiation.

Linalool is a very important flavouring compound found in plants which is used in food and beverages. Linalool has been traditionally detected by analytical instruments such as gas chromatography (GC) coupled with mass spectroscopy(MS) which are not suitable for routine tests. For fast and low cost detection of chemical compounds electrochemial sensors are most suitable. Screen printed carbon electrode (SPCE) is one of the most popular and low cost device used for detection of chemical compounds. In this article we present the detection of linalool using a low cost preannodized commercial screen printed carbon electrode (SPCE). Traditionally electrochemical sensors are used in two terminal mode, however three terminal analysis of electrochemical sensors are found to be more rationale and accurate. In this paper we have analyzed detection of linalool by an advanced three terminal analysis. First we have performed cyclic voltammetry(CV) of the SPCE which showed clear oxidation peaks at different concentration of linalool. The input-output data of the CV has been used for analysis of the impedance of the SPCE.The impedance model of the SPCE was estimated by autoregressive moving average with exogenous inputs(ARMAX) modelling technique using the CV data. The three terminal impedance fitting revealed the values of electrical parameters and the parasitic elements at different linalool concentration. The stability limits of the SPCE was also determined from the pole-zero and Nyquist plots of the estimated models. Impedance behaviour to frequency of the SPCE was further analyzed by impedance plot( 𝒁 vs −𝒁 ′ ) from which we are able to relate the CV scan rate to the impedance of the SPCE. Finally the sensitivity and repeatability of the SPCE was determined using a measurement circuit.

Portability is one of the essential keys in the development of modern analytical devices. Screen printing technology is an established technology for both chemical and biosensor development. Screen printing technology has been used to generate a variety of electronic sensors that are rapid, cost-effective, on-site, real-time, inexpensive, and practical for use in healthcare, environmental monitoring, industrial monitoring, and agricultural monitoring. This review aims to describe recent research progress related to the development and improvement of screen-printed electrodes (SPEs). We also demonstrate the wide range of applications, also highlighting the market directions and the need for novel devices to be used by non-specialists. Finally, we conclude and provide an overview of the constraints and future opportunities of SPEs in biosensor application.
