148 Nanosensors: Physical, Chemical, and Biological
use epitaxially grown QDs for in situ biosensing, mainly due to the ease of
detection.
QD synthesis can be tailored to meet specic requirements, with core,
shell, and coating characteristics all affecting photochemical properties. QDs
may be manufactured with diameters ranging between broad limits starting
from a few nanometers to as large as a few micrometers. Size distributions
are controllable within 2% using accurate growth techniques, involving high
annealing temperatures (Jamieson et al. 2007).
3.2.3.1  CdSe/ZnS Core/Shell QDs
CdSe–ZnS core/shell QDs are prepared using synthetic techniques involv-
ing growth and annealing of organometallic precursors at high temperature.
