In continuation of the previous post, I ran the pore processing software for two samples (t=0 and t=150 min). The following histograms show the pore parameters and the difference in the pore size and numbers between the two samples. I…

TEM images of pnc-Si incubated in DMEM(-FBS)
There has been uncertainty with process of dissolution of pnc-Si in cell growth media. Whether the media enters the pores and ‘eats away’ the material leading to increase in pore sizes and eventually complete degradation was the question. Thinning of…
W613 Discoloration
Given the mixed results of discoloration of RTPed samples from W613, which include no discoloration until 7 days (when the experiment was started within 2 hours of RTPing), and discoloration within 2 days (experiment started 8 days after RTP) I…
Chemical Stability of 30nm Samples with RTP Treatment
Previously I ran a chemical stability study of samples from W613, which has a 30 nm thick pnc-Si layer. In that study complete failure of untreated samples was observed by 18 hours in cell culture, which was not a significant…
Membrane stability in cell culture: various treatment conditions
Four different post-production treatments with the objective of improving membrane stability in culture were run last week on W615, a pinholed wafer laden with the circular features we have been seeing recently. I ran four different conditions for cell culture:…
Membrane Stability in Cell Culture
Last week I ran cell culture growth experiments on RTPed (800C 5 minutes in Ar) samples from W567 (single slit 100um x 1000um). For this study I tracked discoloration w/cells, membrane stability w/cells, and the bead assay w/cells to see…
Incubator versus Benchtop
(Transferred from old blog) From the above discoloration array it can be inferred that the RTP treated samples in the incubator are discoloring in much slower rate than the ones on the benchtop. Thus, incubator conditions prevent the chips from…
Effect of salt on pores (benchtop)
(Transferred from old blog) The above TEM images show that RTP (800C, 5 min) treated samples (from W334) have their pores intact in salt over a period of time! 1M and 2M NaCl solutions were used and TEM samples were…
