An easy fabricated, simple control and label-free micro-detection system was demonstrated in a PDMS chip and a new method to distinguish particle’ size in a FBG-FP cavity is exhibited. In our experiment, The period of FBG is 535.5 nm and the left and right length of the FBG is 5 mm and 3 mm, respectively. An amplified spontaneous emission (ASE) source with wavelength from 1528 nm to 1573 nm is coupled into the input fiber. The output signal is detected by an optical spectral analyzer (OSA, MS9740A) with a resolution of 0.03 nm. Two 25-μm particles pass through the cavity continuously and the flow rate is about 5 μL hr-1. The high-speed OSA clearly shows a rapid spectral change when a particle passes through the cavity

Preparation and Size Control of Sub-100 nm Pure Nanodrugs
Pure nanodrugs (PNDs), nanoparticles
consisting entirely of drug
molecules, have been considered as promising candidates for next-generation
nanodrugs. However, the traditional preparation method via reprecipitation
faces critical challenges including low production rates, relatively
large particle sizes, and batch-to-batch variations. Here, for the
first time, we successfully developed a novel, versatile, and controllable
strategy for preparing PNDs via an anodized aluminum oxide (AAO) template-assisted
method. With this approach, we prepared PNDs of an anticancer drug
(VM-26) with precisely controlled sizes reaching the sub-20 nm range.
This template-assisted approach has much higher feasibility for mass
production comparing to the conventional reprecipitation method and
is beneficial for future clinical translation. The present method
is further demonstrated to be easily applicable for a wide range of
hydrophobic biomolecules without the need of custom molecular modifications
and can be extended for preparing all-in-one nanostructures with different
functional agents

Carbon Nanoparticle-based Ratiometric Fluorescent Sensor for Detecting Mercury Ions in Aqueous Media and Living Cells
A novel nanohybrid ratiometric fluorescence
sensor is developed for selective detection of mercuric ions (Hg<sup>2+</sup>), and the application has been successfully demonstrated
in HEPES buffer solution, lake water, and living cells. The sensor
comprises water-soluble fluorescent carbon nanoparticles (CNPs) and
Rhodamine B (RhB) and exhibits their corresponding dual emissions
peaked at 437 and 575 nm, respectively, under a single excitation
wavelength (350 nm). The photoluminescence of the CNPs in the nanohybrid
system can be completely quenched by Hg<sup>2+</sup> through effective
electron or energy transfer process due to synergetic strong electrostatic
interaction and metal–ligand coordination between the surface
functional group of CNPs and Hg<sup>2+</sup>, while that of the RhB
remains constant. This results in an obviously distinguishable fluorescence
color variation (from violet to orange) of the nanohybrid solution.
This novel sensor can effectively identify Hg<sup>2+</sup> from other
metal ions with relatively low background interference even in a complex
system such as lake water. The detection limit of this method is as
low as 42 nM. Furthermore, the sensing technique is applicable to
detect Hg<sup>2+</sup> in living cells
