Biosensing based on light absorption of nanoscaled gold and silver particles.

Analytical chemistry

Frederix F, Friedt JM, Choi KH, Laureyn W, Campitelli A, Mondelaers D, Maes G, Borghs G.
PMID: 14670050
Anal Chem. 2003 Dec 15;75(24):6894-900. doi: 10.1021/ac0346609.

The absorption spectrum of noble metal spherical nanoparticles is known to be strongly influenced by the dielectric constant of the surrounding material, and as such, these particles are well suited for biosensing applications. To perform biosensing using nanoparticles on...

Langmuir. 2007 Jan 16;23(2):443-51. doi: 10.1021/la061951e.

Tantalum pentoxide (Ta2O5) is a promising material for the realization of biological interfaces because of its high dielectric constant, its high chemical stability, and its excellent passivating properties. Nevertheless, the deposition of highly organized silane SAMs to realize well-defined...

Multifunctional nanomechanical systems via tunably coupled piezoelectric actuation.

Science (New York, N.Y.)

Masmanidis SC, Karabalin RB, De Vlaminck I, Borghs G, Freeman MR, Roukes ML.
PMID: 17690289
Science. 2007 Aug 10;317(5839):780-3. doi: 10.1126/science.1144793.

Efficient actuation is crucial to obtaining optimal performance from nanoelectromechanical systems (NEMS). We employed epitaxial piezoelectric semiconductors to obtain efficient and fully integrated NEMS actuation, which is based on exploitation of the interaction between piezoelectric strain and built-in charge...

Gold nanoparticle dimers for plasmon sensing.

Langmuir : the ACS journal of surfaces and colloids

Cheng Y, Wang M, Borghs G, Chen H.

The relative strengths of Rashba and Dresselhaus terms describing the spin-orbit coupling in semiconductor quantum well (QW) structures are extracted from photocurrent measurements on n-type InAs QWs containing a two-dimensional electron gas (2DEG). This novel technique makes use of...

Andreev reflection at high magnetic fields: evidence for electron and hole transport in edge states.

We have studied magnetotransport in arrays of niobium filled grooves in an InAs/Al(x)Ga(1-x)Sb heterostructure. The critical field of up to 2.6 T permits one to enter the quantum Hall regime. In the superconducting state, we observe strong magnetoresistance oscillations,...
