Figure 4From: Naturally occurring nanoparticles from English ivy: an alternative to metal-based nanoparticles for UV protectionBiodegradability of ivy nanoparticles. The isolated ivy nanoparticles were incubated without (A) or with (B) Proteinase K at 37°C for 30 min. The structure of the samples was then analysed with AFM using tapping mode.Back to article page
