    Metal-Organic Frameworks for the Development of Biosensors: A Current Overview2018In: Biosensors, ISSN 2079-6374, Vol. 8, no 4, article id 92Article, review/survey (Refereed)
    Abstract [en]

    This review focuses on the fabrication of biosensors using metal-organic frameworks (MOFs) as recognition and/or transducer elements. A brief introduction discussing the importance of the development of new biosensor schemes is presented, describing these coordination polymers, their properties, applications, and the main advantages and drawbacks for the final goal. The increasing number of publications regarding the characteristics of these materials and the new micro- and nanofabrication techniques allowing the preparation of more accurate, robust, and sensitive biosensors are also discussed. This work aims to offer a new perspective from the point of view of materials science compared to other reviews focusing on the transduction mechanism or the nature of the analyte. A few examples are discussed depending on the starting materials, the integration of the MOF as a part of the biosensor and, in a deep detail, the fabrication procedure.

    Hydrazine-Free Facile Synthesis of Palladium-Tetrakis(Triphenylphosphine)2019In: European Journal of Inorganic Chemistry, ISSN 1434-1948, E-ISSN 1099-1948, no 14, p. 1951-1955Article in journal (Refereed)
    Abstract [en]

    We present an easy and very efficient procedure for the synthesis of Pd(PPh3)(4) using nontoxic reducing agents. The complex is obtained in a remarkable 83 % yield, and the method can be scaled up. A very detailed spectroscopic and spectrometric characterization is reported.

    Fast and Robust Synthesis of Metalated PCN-222 and Their Catalytic Performance in Cycloaddition Reactions with CO22019In: Organometallics, ISSN 0276-7333, E-ISSN 1520-6041, Vol. 38, no 18, p. 3429-3435Article in journal (Refereed)
    Abstract [en]

    A simple and quick setup for the synthesis of PCN-222 and of a variety of metalated PCN-222(Co, Ni, Cu, and Zn), using of a microwave reactor, is reported for CO2 fixation. Metalation of prophyrins by microwave heating has been evaluated through UV-vis titration. PCN-222(M) were obtained in a three-step, one-pot reaction in a remarkable 72% yield in only 30 min. The materials have been characterized using a variety of techniques. A study of CO2 fixation through cycloaddition with epoxides and azidirines using metalated PCNs as catalysts is described. Cyclic carbonates and oxazolidinones were formed using CO2 at atmospheric pressure under mild conditions. Higher activity was observed when PCN-222(Co) was used compared to that with PCN-222(Ni, Cu, Zn).

    Molecularly Imprinted Polymer-Based Hybrid Materials for the Development of Optical Sensors2019In: Polymers, ISSN 2073-4360, E-ISSN 2073-4360, Vol. 11, no 7, article id 1173Article, review/survey (Refereed)
    Abstract [en]

    We report on the development of new optical sensors using molecularly imprinted polymers (MIPs) combined with different materials and explore the novel strategies followed in order to overcome some of the limitations found during the last decade in terms of performance. This review pretends to off er a general overview, mainly focused on the last 3 years, on how the new fabrication procedures enable the synthesis of hybrid materials enhancing not only the recognition ability of the polymer but the optical signal. Introduction describes MIPs as biomimetic recognition elements, their properties and applications, emphasizing on each step of the fabrication/recognition procedure. The state of the art is presented and the change in the publication trend between electrochemical and optical sensor devices is thoroughly discussed according to the new fabrication and micro/nano-structuring techniques paving the way for a new generation of MIP-based optical sensors. We want to off er the reader a different perspective based on the materials science in contrast to other overviews. Different substrates for anchoring MIPs are considered and distributed in different sections according to the dimensionality and the nature of the composite, highlighting the synergetic effect obtained as a result of merging both materials to achieve the final goal.
