laser flash photolysis studies of selected amphiphilic porphyrin derivatives used as biofilm photodegradative materials https://vital.seals.ac.za/vital/access/manager/Repository/vital:45008 9 for E.

The quaternized derivatives are found to have higher ability to significantly suppress the biofilms of both S. aureus and E. coli in vitro. Therefore, this demonstrates that they are potentially suitable photosensitive agents for PACT use. The TD-B3LYP/LanL2DZ calculations were performed to evaluate the singlet excitation energies of quaternized and non-quaternized porphyrins in vacuo. Our study shows excellent agreement between time-dependent density-functional theory (TD-DFT) excited energies and experimental S1 > S0 excitation energies. The small deviation observed between the calculated and experimental spectra arises from the solvent effect. The excitation energies observed in these UV-visible spectra mostly originated from electron promotion between the highest occupied molecular orbital (HOMO) for the less intense band and the HOMO−1 for the most intense band of the ground states to the lower unoccupied molecular orbital (LUMO) of the excited states.]]> Wed 03 Nov 2021 22:10:59 SAST ]]> Naked Eye and Colorimetric Detection of Cyanide with a 1, 3‐Diethyl‐2‐thiobarbituric Acid Substituted Ferrocene Chemosensor https://vital.seals.ac.za/vital/access/manager/Repository/vital:45006 Wed 03 Nov 2021 21:55:31 SAST ]]> Photocytotoxicity of heavy-atom-free thiobarbituric acid functionalized pyrene derivatives against MCF-7 cancer cells https://vital.seals.ac.za/vital/access/manager/Repository/vital:45005 Wed 03 Nov 2021 21:44:14 SAST ]]> Photodynamic antimicrobial action of asymmetrical porphyrins functionalized silver-detonation nanodiamonds nanoplatforms for the suppression of Staphylococcus aureus planktonic cells and biofilms https://vital.seals.ac.za/vital/access/manager/Repository/vital:45004 Wed 03 Nov 2021 20:59:57 SAST ]]> Photophysicochemical behaviour of phenoxy propanoic acid functionalised zinc phthalocyanines when grafted onto iron oxide and silica nanoparticles: Effects in photodynamic antimicrobial chemotherapy https://vital.seals.ac.za/vital/access/manager/Repository/vital:44389 Wed 01 Sep 2021 14:26:03 SAST ]]> Aluminum corrosion retardation properties of acetamidophenoxy phthalocyanines: Effect of central metal https://vital.seals.ac.za/vital/access/manager/Repository/vital:44386 4 > 3.
