SUMMARY:Physics-Biology interface seminar: Quan Li - Laboratoire Aimé Cott
 on\, Salle Balmer (Batiment 505) - 2 Mai 18 11:00
DESCRIPTION:Nanodiamond based quantum sensors for biological applications\n
 Quan Li (Chinese University of Hong Kong\, China)\nSpecial location: Labor
 atoire Aimé Cotton\, Orsay\n\nNanodiamond (ND) with Nitrogen-vacancy (NV)
  centers serves as promising bio-sensor due to its excellent bio-compatibi
 lity\, high photo-stability\, and the long spin coherence time at room tem
 perature. However\, the complicated biological environment\, e.g. in a sin
 gle cell\, imposes stringent requirements on the sensor probes to be inter
 nalized. In this talk\, I will discuss the requirements on nanodiamond as 
 intra-cellular sensor\, and the possible strategies that will enable vario
 us bio-sensing measurements. I will start with the understanding of nanodi
 amond-cell interfaces\, from anchoring of ND on the plasma membrane to the
 ir internalization\, and eventually to their intracellular trafficking. Ot
 her than the conventional three-dimensional trajectories tracking of the N
 D\, it is also possible to track their orientations (rotation)\, providing
  additional information of the intracellular environment. One problem with
  NV based bio-sensing is that the NV center is less sensitive to certain p
 arameters such as temperature and pressure\, and not at all response to ma
 ny other important biochemical parameters such as pH and non-magnetic biom
 olecules. I will also discuss possible schemes of constructing nanodiamond
  based hybrid sensors\, which lead to significantly enhanced sensitivity a
 nd/or potentially enable the measurement of various biochemical parameters
  using NV based quantum sensing.\n
