In Vitro Antimicrobial Studies of Mesoporous Silica Nanoparticles Comprising An...
Filipe, Luís; Sousa, Telma; Silva, Dário; Santos, Miguel; Ribeiro Carrott, Manuela; Poeta, Patrícia; Branco, Luís; Gago, SandraThe combination of active pharmaceutical ingredients in the form of ionic liquids or organic salts (API-OSILs) with mesoporous silica nanoparticles (MSNs) as drug carriers can provide a useful tool in enhancing the capabilities of current antibiotics, especially against resistant strains of bacteria. In this publication, the preparation of a set of three nanomaterials based on the modification of a MSN surface ...

Oliveira, Luísa; Borges, Isabel; Silva, Dário; Durão, Ana C.; Soares, António O.Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is a major pest of tomato (Solanum lycopersicum L.) crops produced in the Azorean greenhouses. Despite the major concerns, no systematic study is available to describe population dynamics of T. absoluta and its natural enemies. The objective of this study was to compare the abundance of the pest (eggs and larvae) and its native natural enemies, in greenho...

IAQ can be affected by numerous factors, from outdoor pollutants that get indoors through ventilation to building materials, furnishings, and activities carried by the building occupants. Exposure to air pollutants has been linked ...
Synthesis and Antibacterial Activity of Ionic Liquids and Organic Salts Based o...
Ferraz, Ricardo; Silva, Dário; Dias, Ana Rita; Dias, Vitorino; Santos, Miguel M.; Pinheiro, Luís; Prudêncio, Cristina; Noronha, João PauloThe preparation and characterization of ionic liquids and organic salts (OSILs) that contain anionic penicillin G [secoPen] and amoxicillin [seco-Amx] hydrolysate derivatives and their in vitro antibacterial activity against sensitive and resistant Escherichiacoli and Staphylococcusaureus strains is reported. Eleven hydrolyzed β-lactam-OSILs were obtained after precipitation in moderate-to-high yields via the n...
