Recent literature on SERS substrates points at flexible cellulose, 3D-printed metals, and uniformity-engineered nanostructures. We review what is useful for industrial work and what stays in the lab.
Six vendors that matter for bioreactor monitoring - what each one is good at, what they are not, and the methodology we used to scope the field down from the full process Raman market.
A companion to the non-ranked Spectrane process Raman buyer's guide. Ten vendors ordered on process-readiness, total cost of ownership, integration depth, chemometric maturity, and application coverage.
Six recent peer-reviewed PAT papers worth a read: lean chemometrics for spectroscopic models, simpler bioprocess Raman regressions, at-line terahertz for crystallinity, and PAT-with-machine-learning past the bioreactor.
Three recent papers shift the calibration-transfer conversation: a low-rank fine-tuning method for deep Raman models, a vendor-to-vendor PDS/SST study, and single-compound shortcuts that sidestep paired transfer sets.
EMA's March 2026 Q&A on 3D-printed solid oral doses accepts inline NIR and Raman spectroscopy for unit-level rejection, anchoring personalised micro-batches in the QbD and RTRT framework.
March-May 2026 in ACS Analytical Chemistry: three threads for process analytics - close-focus Raman probes for turbid streams, deep-learning chemometrics, and open-source spectroscopy tooling.
USP chapters 858 (Raman Spectroscopy) and informational 1858 replaced chapter 1120 on 1 August 2020. Almost six years on, handheld identity testing is the workhorse application; compendial method adoption is uneven.
Five recent papers sketch where deep-learning chemometrics sits versus PLS for process Raman: a public bioprocess benchmark, two classifier benchmarks, self-supervised pre-training, and an explainability tool for GMP.
Recent peer-reviewed work on time-gated Raman - 512-pixel SPAD line arrays, Fourier-transform variants, and time-resolved use beyond fluorescence rejection - and what process-analytics teams can take from it.
A scan of vendor press rooms over the March-May 2026 window turns up no new process Raman analyzers from the major suppliers. The visible motion was in adjacent inline analytics and lab-grade Raman.
