Journal ArticleDOI
Graphene oxide exhibits differential mechanistic action towards Gram-positive and Gram-negative bacteria.
Thiruchelvi Pulingam,Kwai Lin Thong,Md. Eaqub Ali,Jimmy Nelson Appaturi,Ignatius Julian Dinshaw,Zhan Yuin Ong,Bey Fen Leo +6 more
TL;DR: Characterizations of synthesized GO confirmed the transition of graphene to GO and the antibacterial activity of GO was concentration and time-dependent and loss of membrane integrity in bacteria was enhanced with increasing GO concentrations and this corresponded to the elevated release of LDH in the reaction medium.
Journal ArticleDOI
Rapid and sensitive detection of Salmonella with reduced graphene oxide-carbon nanotube based electrochemical aptasensor
Jimmy Nelson Appaturi,Thiruchelvi Pulingam,Kwai Lin Thong,Shalini Muniandy,Noraini Ahmad,Bey Fen Leo +5 more
TL;DR: A biosensor using reduced graphene oxide-carbon nanotubes (rGO-CNT) nanocomposite via the hydrothermal method for accurate and rapid label-free electrochemical detection of pathogenic bacteria such as Salmonella enterica is developed.
Journal ArticleDOI
Carbon nanotube-based aptasensor for sensitive electrochemical detection of whole-cell Salmonella.
Rakibul Hasan,Thiruchelvi Pulingam,Jimmy Nelson Appaturi,Anis Nadyra Zifruddin,Swe Jyan Teh,Teck Wei Lim,Fatimah Ibrahim,Bey Fen Leo,Kwai Lin Thong +8 more
TL;DR: The results showed that the impedance measured at the ssDNA/MWCNT/ITO electrode surface increased after exposure to Salmonella cells, which indicated successful binding of Salmoneella on the aptamer-functionalised surface.
Journal ArticleDOI
Synthesis, characterization and cytotoxicity studies of nanocrystalline cellulose from the production waste of rubber-wood and kenaf-bast fibers
Duolikun Tuerxun,Thiruchelvi Pulingam,Nurul Izza Nordin,You Wei Chen,Jahangir Kamaldin,Nurhidayatullaili Muhd Julkapli,Hwei Voon Lee,Bey Fen Leo,Mohd Rafie Johan +8 more
TL;DR: In this article, nanocrystalline cellulose (NCC) was successfully prepared from raw rubberwood fiber (RRaw) and raw Kenaf-bast fiber (KRaw) via a series of multi-step chemical-mechanical purification techniques, namely, alkalization treatment, hydrogen peroxide bleaching and acid hydrolysis.
Journal ArticleDOI
Synergistic antibacterial actions of graphene oxide and antibiotics towards bacteria and the toxicological effects of graphene oxide on human epidermal keratinocytes.
Thiruchelvi Pulingam,Kwai Lin Thong,Jimmy Nelson Appaturi,Nurul Izza Nordin,Ignatius Julian Dinshaw,Chin Wei Lai,Bey Fen Leo +6 more
TL;DR: The combinatorial antibacterial activity of GO and antibiotics were found to increase when compared to GO or antibiotic alone, which was attributed to the ability of GO to disrupt bacterial membrane to allow for better adsorption of antibiotics.
