Nanodiamond Drug Device Could Transform Cancer Treatment

... in their study, Ho and his colleagues embedded millions of tiny drug-carrying nanodiamonds in the FDA-approved polymer parylene. Currently used as a coating for implants, the biostable parylene is a flexible and versatile material resembling plastic wrap. A substantial amount of drug can be loaded onto clusters of nanodiamonds, which have a high surface area. The nanodiamonds then are put between extremely thin films of parylene, resulting in a device that is minimally invasive...

Nanodiamond conjugate induces cancer cell death and inhibits tumorigenesis

Researchers in Taiwan have manipulated nanodiamond (ND), a carbon nanomaterial, to covalently link paclitaxel for cancer drug delivery and therapy. Paclitaxel was bound to the surface of 3–5 nm sized ND through a succession of chemical modifications. The ND-paclitaxel conjugation was measured by atomic force microscopy and nuclear magnetic resonance spectroscopy, and confirmed with infrared spectroscopy by the detection of deuterated paclitaxel.

Schematic setup of Trestles LH10-fs/CW laser system with built-in pump laser

Del Mar Photonics supply Trestles lasers as stand alone system, or as a one-box system with built-in DPSS pump laser.
The price of the system with DPSS pump depends on required output power.


The standard tuning elements indicated below are used in CW Ti:Sapphire lasers such as Trestles CW or Trestles fs/CW.

Those elements are also sold separately as standrad items or as a custom made components.

1) Thick etalon - request a quote
Thickness - 3 mm, diameter - 20 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.

2) Thin etalon - request a quote
Thickness - 200 um, diameter - 15 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.

3) Birefringent filter BRF - request a quote

We use a 3-plate assembled BRF (Lyot filter) with adjustable motorized mount (see attached drawing).

Total losses introduced into the cavity by the filter are 5% of the laser’s output power. The FSR is defined by the thinnest plate and equals to around - 1.3*1014 Hz, while the maximum width is controlled by the thickest plate and equals to approx. 3.1*1012 Hz.

Dimensions of plate assembly ('filter' in the picture): dia 44.5 mm, t=13.5 mm. It should be properly aligned (Brewster to the beam) and rotated by some rotating mount around its axis to provide wavelength tuning.
