Journal ArticleDOI
Hydrodynamic Trapping of Swimming Bacteria by Convex Walls.
TL;DR: The results demonstrate that the main mechanism for wall entrapment is hydrodynamic in nature and show the possibility of inhibiting cell adhesion, and thus biofilm formation, using convex features of appropriate curvature.
Journal ArticleDOI
Transmigration characteristics of breast cancer and melanoma cells through the brain endothelium: Role of Rac and PI3K
Judit Molnár,Csilla Fazakas,János Haskó,Orsolya Sipos,Krisztina Nagy,Ádám Nyúl-Tóth,Attila Farkas,Attila Gergely Végh,György Váró,Peter Galajda,István A. Krizbai,Imola Wilhelm +11 more
TL;DR: It is suggested that targeting the PI3K/Akt pathway may represent a novel opportunity in preventing the formation of brain metastases of melanoma and breast cancer.
Journal ArticleDOI
Microfluidic study of the chemotactic response of Escherichia coli to amino acids, signaling molecules and secondary metabolites.
Krisztina Nagy,Orsolya Sipos,Sándor Valkai,Éva Gombai,Orsolya Hodula,Ádám Kerényi,Pál Ormos,Peter Galajda +7 more
TL;DR: The usability of the microfluidic platform is demonstrated in co-culturing experiments, where it was shown that various factors released by P. aeruginosa affect the dynamic spatial rearrangement of a neighboring E. coli population, while surface adhesion of the cells is also modulated.
Journal ArticleDOI
Interaction of Bacterial Populations in Coupled Microchambers
TL;DR: When culturing bacteria in artificial microhabi-tats, such as in microfluidic devices, microcham-bers and microreactors, the ecological and microbi-ological aspects must be considered.
Journal ArticleDOI
Integrated optical biosensor for rapid detection of bacteria
Anna Mathesz,Sándor Valkai,Attila Újvárosy,Badri L. Aekbote,Orsolya Sipos,Balázs Stercz,Béla Kocsis,Dóra Szabó,András Dér +8 more
TL;DR: It is shown that an integrated optical Mach-Zehnder interferometer, a highly sensitive all-optical device made of a cheap photopolymer, can be used as a powerful lab-on-a-chip tool for specific, labelfree detection of proteins.
